Does anyone know, other than ebay, where I could find original floor mats to match the color?
Also, are there any better floor mats to use instead?
Thanks

Has anyone purchased/installed XM or Sirius radio in their '96-'99 Auroras?
I was wondering about how much it is and where they put the reciever etc. and how people liked it.
Thanks
Greg
Also try http://www.car-part.com - lets you search junkyards. Or eBay.
Regarding satellite radio, I've had XM (Delphi SkyFi) in my Aurora for about 15 months. I really, really love it. I originally mounted the antenna by the passenger side A-pillar, and just ran the antenna wiring down the door frame/under the glovebox and over. Unfortunately, that was in February, and by May the trees had blossomed on my way to work, so I was losing signal. I've subsequently mounted a Terk (flatter, magnetic) antenna in front of my sunroof, in the center of the car, still running down the passenger-side A-pillar. I'm running power from the secondary cigarette lighter (my primary doesn't work, and I haven't had time to disassemble the center console yet to fix it), and running the cassette adapter. I've run the wires over and up the "seam" going up the dash on the passenger side.
It took me awhile to find the right mount, but I'm using a Pro-Fit Ultimount to mount the SkyFi just to the right of the Driver Info Center (and up above the passenger's knees :-)
Hope this helps,

im hoping to have my bumper painted soon, gotta get this ugly ugly bra off, but it looks better than the hole in the old bumper...lol
W, your paint code should either be on the spare tire cover (I think this is on later cars) or somewhere on the side of the trunk (may have to pull back the carpeting a little) until you can find the RPO sheet. The paint code is usually on the lower line and it follows the lettering "BCCC" which stands for Base Coat Clear Coat.
I think there's a listing of paint codes on Zincster's site, if its' still up (captured it all into a 49 MB PDF file a long time ago for future reference :-)

im hoping to have my bumper painted soon, gotta get this ugly ugly bra off, but it looks better than the hole in the old bumper...lol
Having said that, I've not looked for it myself, but have had a body shop guy tell me how hard it was to find.
good luck.
also, i posted this in a different part of the forum... im getting a replacement bumper painted, and im STRONGLY considering having the side grey plastic painted to match the color of the car, what do you guys think? id keep the front/back 2 tone, but i think it would look -slightly- lower and better from the side by doing this, this is were i got the idea from
http://www.cardomain.com/memberpage/323508
a few intrigue owners did it, i think it made it look lower/sportier...what do you guys think?
the one in the link looks kinda like a LaSabre now...
Of the luxury cars, only the Cadillac DTS and the Mercedes Benz 320 were "better" than my Aurora. I'm not sure what "better" means, except, maybe I'd accept one of these cars in an even-steven trade for mine.
A larger group of the luxury cars were, to me, more or less the same as mine, but I wouldn't swap my car for them. This included the Pontiac Bonneville, the Buick LeSabre, the Mercury Grand Marquis, the Lexus 330(? I think that's the number), and the BMW 5-series. Some of these cars are really way beyond the Aurora in cost and gee-whiz, but it's all personal taste, and the overall content that you are willing to pay for. For me, these things count: the sheet metal, the interior comfort, basic amenities, and to a lesser extent extra content. Some of the foreign cars just didn't compare to the Aurora with respect to interior comfort. I think the same thing can be said about the sheet metal, too. For many Americans, a car is almost an artistic endeavor. The sheet metal matters. Even on a sedan. But consider the BMWs -really, how ugly can a car get? But, they are wildly popular, so I guess it's a case of different strokes for different folks. You know, some people keep pet pigs, too.
There were three luxury cars that I could never imagine being happy with. The Cadillac CTS, the Saab 9-5, and the BMW 3-series. Just too "European" for me. A ride that feels like a jittery go-cart - I think they euphemistically call it "road feel" or "feedback" or "sport suspension" or "handling". And acres and acres of black plastic on the dash, on the doors, on the console, everywhere they could think of. And the cabins just feel small and dinky - and you know, our Auroras don't have really large cabins to begin with. I guess that BMW has defined a fairly broad and profitable market with the 3-series, and if Cadillac wants part of it, they have to play the game with the CTS. I like the CTS on the outside, but the inside and the ride just don't compare with the Aurora. I'm disappointed, because I hoped I could get a CTS in 3 or 4 years when our family is ready for it's next car.
At the end of the day, I left in my Aurora, thinking how lucky I was to own just about the best car around.
I also got to drive the 2004 Corvette, Chevy SSR, and the GTO - - really a fun day. If your town is one of the 20+ cities on the schedule for this this promotion - just do it. And take your teenage son, or your teenage wife, if you have one, or both.
How can I tell what cities it will be coming to? I've never even heard of it... Thanks!
It was way too crowded and the lap was too short. But thats South Florida for ya. Also we couldn't hardly push the cars before they started yelling at us.
I agree with you 100% on how well the Aurora actually does compared to the other cars. Only the 5-series and SRX V8 (with every option) I preferred over the Aurora. But those cars were well over $55k. I'd think I be set for a while for a Black 03 Aurora with nav and 12-disc.
But as far as the show, the free lunch was cool but you'd be alot better off going to the dealers. I don't know how, but I got invited there and they had all my info already. They were taking people but you had to fill some paperwork out.
The interior is the worst, though. No way on earth I could warm up to that. The seats are thankfully right out of an Aurora except for the suede inserts. They Bonnie seats used to be different. But they took an SSEi, and stuck fake carbon fiber on everything. The door handle surrounds, around all the vents (which are still those stupid eyeball things), and even on the steering wheel. It's like the SSEi interior wasn't boy-racer enough, so lets slap fake carbon fiber everywhere... That'll class it up... The white-faced gauges aren't great either, because they are too close together and busy, and the scripting/spacing of the markings is not good. It's too spaced out and ambiguous. It isn't clear where 60mph actually is, for example. You can get a feel for about where it is, but at a glance it sucks. They even manage to ruin the ergonomics. The heated seat and traction control button are way way up where the cubby is on our cars (there's no cubby) in front of the shifter. So the shifter pretty much blocks you from even seeing the traction control button, and it's a real reach to push it.
The exhaust tips are Corsa styled, but not executed nearly as well. They seem smaller, and certainly not of the same quality steel. It's a nice look, but in the details it's not even close to the Corsa tip.
It's a good thing it has a solid platform, a great V8, and supposedly a great ride, because that's all it has going for it. I was expecting to like it a lot more than I did. I think in red I could warm to the exterior even more (it's not a bad looking car) but the interior is abysmal. It's not even like plain and boring, it's like actively awful...
There was a sales guy who told me I looked like I was meant for the car. I explained my only interest in it (owning an Aurora and all), and he said the Aurora was a great car and that the dealership could use my car if I was interested in a trade. I thought that was funny, looking around at the overly-styled Pontiacs and the underly-styled Buicks (don't get me wrong, Buick has an attractive conservative style, less bland than the previous Caddy styling) and thinking "hell ya you could use a car like the Aurora in here..." I told him the engine was the only appealing part of the car, and that I much prefered my Aurora, at which point he just sort of walked off.
I was short on time (it was going to rain again, *sigh*) so I took it for a 15-minute spin. The idle exhaust sound is nice, but I prefer the sound of my airbox-modded Aurora when putting my foot into it. It didn't seem to handle that much better than my Aurora going around curves (though I can tell that, with 83k on my '98, it's going to be time soon for struts and shocks). The ride quality of the GXP quite frankly sucked (the road harshness/bouncing was quite evident, but not when I went back the same way with my Aurora). Not sure if it's the suspension setup or the 18" wheels/tires. I obviously couldn't check inflation, and the car hadn't been at the dealer for too long. I also didn't like the interior faux carbon-fiber look, or the "overly-busy" look (the dual climate control was not intuitive to figure out). I didn't want to stomp on the car, but wasn't overly impressed with the acceleration over my airbox-modded Autobahn '98.
I find the exterior styling not bad (it's the best-looking Bonneville they've built since '92 - I really can't/won't comment on models before that). The brakes were awesome. I liked the lower trunk liftover/bigger trunk. Headroom in the back seemed no better than my Aurora.
The same day one of the sales guys at my work pulled up in his new 300C Hemi. I'm not a huge fan of the styling on that car, but it's kinda growing on me (I keep thinking "Bentley") and the interior is very nice. For 34k it's a much better value than the GXP (340 hp vs. 275 for the GXP), though I realize the GXP probably handles better and is marketed differently. Still, selling his car at $38k+ is going to be a challenge for GM, so I don't see the incentives going away, or even going down anytime soon.
If nothing else, driving the GXP makes me want to drive a 2002 or 2003 Aurora 4.0. Who knows, I might end up in a used one of those, and shun all of my GM discounts. Or maybe the GXP will grown on me. I'm really in no hurry to move away from the Aurora (may buy a beater to put winter mileage on) since it is, by far, the best car I've ever owned, and my dream car (once I get the Corsa on - probably in July :-)
--Robert
What does GM or Ford even remotely have to compete with this? I definetly dont see anything in GM future except the V-series STS but that well over 60k And the V-series CTS about half a 300C.
As far as the styling of a 300C the front is really good. The way the hood overlaps and the two-part headlights (the yellow bar and round main). The chopped top looks good in black w/tints. But the rear seems very much like they cut costs there big time. The sheetmetal is blah-plain the taillights look off a Kia. It should have had led taillights.
Maybe the SRT-8 will have new ones and a body kit.
it must be that airbox mod making up for .6 L of displacement.....cause stock for stock its about 1.5 seconds faster in the 1/4..........
--Robert
the only published autobahn times ive seen are a 7.9 0-60, with a 15.8 i believe. compared to 6.5 / 14.5 for a gxp. gtp's publish a 6.4-6.8, and 14.6-15.0 - if you want to bench race.
the gxp isn't a car that needs to wind up quite like the aurora. it does, yeah, but ive driven a base model (275hp) eldorado that didn't need to wind up to much, and it had 3.11 gears, with 3.71's, the gxp is a very torquey car, that and they weigh 200lbs less than our classics.
ive seen the gxp a few times (autoshows) and it looks like the 2000+ bonnevilles with a little 2001+ aurora styling. in how its so clean, smooth and not over done. somthing about its lines reminds me a little of the 2001 aurora. and i really like the interior, but im younger so more into the "boy racer" look, but its not really as bad as i thought it would be. i dont like any other pontiac interiors, except the gto and NEW grand prix's are ok.

so that means if a 95 wants the whole tb its $460 + core? jesus....250 for tb, 110 for tq plate, 100 for matching tb mount - or does the tq plate replace the mount? you should ask, because for all the 96-99 guys it was still 250+100.
us 95 guys have a chip option too, but lets not get into that discussion again, i still would like to try that, but all these suspension problems are keeping the funds down.
I coulndt imagine putting my Rora through cones. It would be embarassing.
On a side note, I saw on Real TV (a program on Spike TV) a local oval track had a run what ya brung. They had 2 vettes, a muscle car, a Deville Concours, 2 trucks, and some others. I think the rora what have a nice shot after the vettes crashed. Esp. considering how top heavy tuned the 4.0 is. Starting to wonder if there's any down here lol. Just to see what she'll do.
right now, i turn, the body rolls ALOT before it even turns. if i turn left/right/left very fast and agressive, i can almost go in a strait line and just get the body to rock back in forth (ive only done that 1 time) hopefully that will change with the new equipment, but right now, its the definition of a boat! (140k old suspension too...)
isn't the aurora built off the stiffest fwd plateform that gm makes? i think all the cars are built off a variation of it now
(yeah, i meant 1st gen)
Does anyone think STS springs would help? I'm sure they're stiffer than ours (STS's fat weight). The 98+ STS's springs would bolt right up to a classic? Also which year on the STSs would be the best?
just trying to get it strait.
rsm is a pretty bs company. have you seen the auorora "ss" package? i laugh everytime i look at it, and laugh harder everytime i see the price. usually you get a package discount, not on this, they jack up the price for a package, unless those ss badges cost a few grand.
i dont think sts springs will work, back when eibach made aurora drop springs and 98+ sts springs they had different part numbers.
it took me a year to track down a set of those springs, there was someone else on gmforums that had a set for sale, i can see if i can find there old email address, but it was a year ago or more.
Correct. All Classics have this "torque plate." I'd guess 2001+ also, but I don't know for sure.
Another thing about RSM: when they raised prices last year, they also changed their policy on core charges which are now redeemable only as credits on future purchases. OK for someone planning to buy the SS package. :,)
A good thing is they no longer list a core charge for the spacer. It seemed odd to me that they used to get $100 core charge for a part available from GM new for $13. I had planned to open one up to 80mm myself, but after getting one in my hands, I decided I didn't have the tools to do it. It would probably be a breeze for any competent machine shop.

In Memory of Merry Oldsmobiles
By JERRY GARRETT
The only new car my grandmother bought was a dark green 1951 Oldsmobile Series 98 Deluxe sedan with a Rocket V-8 engine. Family members proudly posed in front of it when Grandma, then 44, drove home from the dealership.
A few days later, she wrapped a telephone pole around it, when she couldn't stop it fast enough. No one was hurt, although the car was a total loss.
"It just had too much power," said Grandma, who never drove again. But for decades she encouraged family members to keep buying Oldsmobiles - 88's and 98's, Starfires and Cutlasses - because, she said, "It proved it's a strong car."
In 1951, it was strong enough to inspire Ike Turner and the Kings of Rhythm to immortalize Olds's amazing new V-8 engine. They arguably created rock 'n' roll in the process.
"Rocket 88" was the first hit for Sam Phillips, and the producer used money from its sales to start Sun Records, which would go on to "discover" Elvis Presley, Jerry Lee Lewis, B.B. King, Johnny Cash and others.
" 'Rocket 88' was where it all started," Phillips would say years later. "It was the first true rock 'n' roll record - the first hit record, anyway."
This was not the first time an Oldsmobile inspired a song. Vincent Bryan wrote the lyrics of "In My Merry Oldsmobile" in 1905 to pay tribute to the toast of the fledgling American auto industry, the Curved Dash runabout from the Olds Motor Works.
Olds, formed in 1897, was, until it went out of business this spring, America's oldest automaker, and the Curved Dash was the early auto sales leader and the first vehicle to be mass produced. (Henry Ford would later automate the assembly process.)
"I don't like the smell of horses," Ransom E. Olds reportedly told those who asked him why he had started his pioneering work on horseless carriages. His first vehicle, built in 1887, was steam-powered. (Gottlieb Daimler is credited with building the first gasoline-powered car about a year earlier.)
The Curved Dash's rise was fortuitous; Olds had designed and built 11 prototypes to be produced at a new factory in Detroit. But the factory burned to the ground; only the heroic act of a foreman, who dragged a lone Curved Dash to safety, kept the company going. Olds returned to his home in Lansing, Mich., where he began reproducing the sturdy little runabout, the only car he had left.
Public demand was stoked by publicity stunts, like having Olds's associate, Roy Chapin (who later headed American Motors), drive a Curved Dash to New York City for the first auto show there, in 1901, to demonstrate the car's durability.
Olds's investors, however, would run him off in 1904. He formed Reo (named from his initials), which outsold Olds for a time; Reo would stay in business until 1975. Olds lived in Lansing until he died in 1950, but never returned to Oldsmobile. His home was later razed for construction of Interstate 496 - the Olds Freeway.
Olds would become, with Buick, the cornerstones of Billy Durant's General Motors in 1908, but no one would get around to incorporating the Oldsmobile name until 1942.
Within G.M., Olds was the "technology division." It was a pioneer in V-8 engines, as early as 1915. Chrome made its automotive debut on 1926 models. Olds offered the first automatic transmission (later named the Hydra Matic) in 1937. The Rocket V-8 made its debut in 1949.
That high-compression engine, and the 88 model in which it was installed, created a sensation. Oldsmobiles dominated Bill France's Nascar racing association in its first three seasons.
"The combination of the Oldsmobile chassis and the Rocket V-8 was unbeatable, in the hands of the right driver," France said years later.
France knew that firsthand: in 1950 he and Curtis Turner, in a Lincoln, would be beaten in the first Mexican Road Race by an Oregon lumberjack, Hershel McGriff, driving an Olds in showroom stock trim. Oldsmobile would hire Mr. McGriff to crisscross the country, making promotional appearances and racing his 88. After finishing ninth in the inaugural Southern 500 in 1950, Mr. McGriff would drive the Olds from South Carolina to Portland, arriving with 15,000 miles on the odometer.
"Those were all hard miles," Mr. McGriff, 74, and still living in Oregon, remembers. "That was one tough little coupe." The prizes he won in five years of racing set him up for life in the lumber business.
Oldsmobiles helped put the Petty family on the road to racing riches, too; Lee Petty drove one to victory in the first Daytona 500, in 1959. His son Richard made his debut there in an Olds convertible.
Olds's performance image was reinforced in the 1960's by models like the turbocharged F-85; the innovative Toronado with front-wheel drive and hideaway headlights; and the 4-4-2, named for its four-on-the-floor shifter, four-barrel carburetor and twin exhaust pipes. The Hurst/Olds, with fancy aftermarket shifter, garish paint and removable T-top roof panels, was a common sight at American racetracks.
Through the 1970's and early 1980's, the popularity of the Cutlass Supreme made Olds the nation's third-best-selling brand. But in the mid-1980's, a sweeping reorganization ordered by G.M.'s chairman, Roger Smith, eviscerated the close-knit Olds "family" - a complete and self-contained company that designed, engineered and produced its own cars. Olds was folded into a new Buick-Olds-Cadillac superdivision.
Suddenly, Oldsmobiles were being built outside Lansing; the local plant was making Buicks. Olds's unique engines were even replaced by Chevy power plants. Insiders complained that Olds had lost not only its identity, but its ability to stand behind its products, address problems and develop models. By the time the reorganization was undone, the damage was irreversible.
In the 1990's, under the outspoken leadership of John D. Rock, Oldsmobile received a last chance to re-establish its identity. New models like the Achieva, Intrigue, Aurora and Alero replaced venerable names like Eighty Eight, Ninety Eight and Cutlass. The Rocket V-8 was discontinued after a 40-year run. Extreme emphasis on motorsports produced A. J. Foyt's world closed-course speed record of 257 m.p.h., plus an Indianapolis 500 victory on Olds's 100th birthday in 1997 (in a predominantly Olds field). But that would not be enough to save the brand.
"Oldsmobile never had to die," an Olds historian, Helen Earley, said. "But G.M. seemed determined to kill it."
In an interview during a vintage car race in 2001, Robert A. Lutz, vice chairman of G.M., said: "The one decision I wish hadn't been made before I got here, was the decision to fold Oldsmobile. I could have done big things with it."
Mr. Lutz, who arrived a year too late, saw in Olds the "boutique car company" he'd envisioned for Plymouth, another discontinued brand, when he was at C

2004 Oldsmobile Alero: Not With a Bang but a Whimper
By JAMES G. COBB
OLDSMOBILE, the oldest American automaker to reach the modern era, died on April 29, 2004, after a long illness complicated by faulty prescriptions and parental neglect. It was 107.
The eldest child of the General Motors Corporation - indeed, it was born 11 years before its adoptive parent - Olds built its reputation with comfortable, stylish, technologically advanced cars for the aspiring middle class.
Olds had been on life support since December 2000, when G.M. said it would shut down the division over four years. Annual sales, which routinely topped 1 million in the mid-1980's (when Olds was the nation's No. 3 car line, after Chevrolet and Ford), had fallen to 125,897 by last year.
Oldsmobile is survived by its parent company, of Detroit, and its siblings: Buick, Cadillac, Chevrolet, GMC trucks, Hummer, Pontiac, Saab and Saturn.
Sometime in the Kennedy administration, my much older sister brought home a boyfriend and a 1953 Olds 98 Holiday hardtop. I, barely in grade school, tolerated the fiancé, but I loved his car.
By the early 60's, that bulbous Olds with its Buck Rogers overtones was already dated. But I recall that it was impeccably maintained and lavishly equipped with the accessories my thrifty father dismissed as "more things to go wrong."
Whenever possible, I would sneak into the Olds to test the power windows, activate the signal-seeking radio and marvel at the automatic headlamp dimmer. But the coolest thing may have been encased in plastic in the middle of the steering wheel: a golden planet with rings, like Saturn.
For a nation obsessed with space exploration, the emblem - and the rocket that replaced it in 1959 - suggested that anyone could be an astronaut: just drive off in a Starfire, a Jetstar or an F-85.
These were cars of unlimited possibilities for an age of unrestricted optimism. For much of the postwar era, an Olds was something you dreamed of owning, just as many people today aspire to a Lexus.
In a measure of how much has changed, for Olds and Detroit, the final Olds is unlikely to rank high on any list of consumer aspirations. That car, a red Alero, rolled off the line at the end of April at the Lansing Car Assembly plant. While that car is destined for the new G.M. Heritage Center, I recently drove one much like it, an Alero GL2 sedan with a sticker of $22,450.
Arctic white with a tan cloth interior and shiny alloy wheels, it was a car much like tens of thousands in the nation's rental fleets, where its compact dimensions are generously described as midsize.
The Alero had no Rocket V-8, making do with a rather noisy 3.4-liter V-6, a pushrod design not unlike the engines that powered Oldsmobiles four decades ago. At least the transmission, a smooth four-speed automatic, and the four-wheel independent suspension were up to date.
There was no golden planet on the steering wheel, just a stylized rocket insignia that dates to Olds's 1997 centennial. But at least the Alero didn't hide its heritage, with the Oldsmobile name in block letters on the rear deck. (When the stylish Aurora arrived in 1995, it seemed ashamed of its parentage: the Olds name appeared only on the radio faceplate.)
Engineered for the mass market, the Alero is surprisingly pleasant running suburban errands. Predictable and stable, it moves out briskly and stops acceptably. The steering is a bit wooden, but fairly quick and reasonably precise. The car has pronounced understeer, a reluctance to turn, but that helps to keep inexperienced drivers out of trouble.
At highway speeds, the dead steering and vague handling do not inspire confidence. The comparably priced Volkswagen Jetta was obviously created with high-speed autobahns in mind, but the Alero seems to suffer from the lowest-common-denominator engineering that has turned many Americans away from Detroit's products.
G.M. has been working to improve its interiors, and the Alero shows belated progress. The dashboard plastic is better, not great, and the pieces seem to have been designed to disguise the glaring gaps between them.
But when you open a door, the first thing you see is a thick rubber strip, like one from a squeegee, tacked into the door sills. The seats are mushy. The back seat cupholder, which binds as it flips down from the console, must have cost about a dime.
Neither a terribly bad car nor an especially good one, the Alero's white-bread mediocrity is typical of the small to midsize cars that Detroit has churned out for years. The Alero is, in fact, a virtual twin of the Pontiac Grand Am. Both are transportation devices, cars for people who don't like cars very much.
Like Plymouth, De Soto or Packard, Olds deserved a better obituary. But the final message is clear: Oldsmobile thrived when it made rocketships for the road. It died when it offered only appliances.
INSIDE TRACK: Little orphan Alero.
We've got some pretty good information in this forum about getting more out of the 4.0L Northstar. It seems to me that the engineering design of a car has to involve trade-offs between comfort, fuel economy, power, and cost. I began to wonder what trade-offs the original design engineers made in our Auroras. I began thinking about friction, and I've been wondering if we could get our cars to this level:
Fuel Economy of 30 mpg,
Power measured at the wheels of 300 hp/300 ft-lbs,
For a cost of $3000 total parts and labor.
All without ruining the smoothness, comfort, and quiet of the Princess.
Is it possible - 30/300/3000?
We're already close on highway mileage (I get 24 mpg - need another 25%), we're already close stock at 250/260 (we're talking just +20% to get to 300), and some of us are already at ~275+ hp with airbox, throttle body, and exhaust mods that come to about $1500-$2000.
Any ideas? Does anybody else want to talk about this?
Ken
Your highway mileage is so dependent on speed, wind (with you or against you), and terrain (are you climbing or going down hill), that saying you want 30 MPG is somewhat meaningless.
As a group we already know how to make the 4.0L breathe better and make available horsepowers up around 275 hp - just on improved air flow alone. However, there are other improvements (more expensive) to air flow that none of us have tried yet. Or, can we reduce friction and increase compression to get just 25 more hp, and at the same time increase fuel economy? As I have read in the hot rod magazines, reducing friction and increasing compression both generally have the effect of increasing fuel economy. How much? - I don't know. Do you think we can get to 30/300/4000? I don't like $4000 as much as $3000, but I believe that we can generate ideas that will bring us a little closer to 30/300/3000 than we are already. If we don't get there, so what?
Ken
If you want better highway MPG, then running the engine slower helps. Any engine mods are likely to cost a lot to get much power.
Some aero work might help too, heck you could shave the mirrors and doorhandles. And trimming the weight can't hurt, though it won't impact level cruising mpg much at all.
To get more power, stroke or bore the engine, and you could try raising the compression as you said. 300hp would be fairly easy on the 4.0 if you didn't care so much about torque, but to keep low-end torque (you'd need it big time with a 3.11 or lower), you're gonna need more displacement.
One expensive way to improve airflow is a turbo or supercharger. This will definitely bump airflow into the engine, and increase power. A turbo, especially one with a wastegate, shouldn't have too much impact on mileage either, at least when you are easy on the gas.
You are talking mega modification and mega money at this point, though. It might be cheaper and easier to drop an SLS/Eldo/Deville powertrain in and work to bump that 275 up to 300 via exhaust and intake work. You'd manage close to 30 mpg with that, I'd bet.
I don't believe the Shelby Series 1 could manage 30 mpg while cruising, and it is much lighter, smaller, and made 320hp from the 4.0. Plus, it had a 6-speed giving it some gearing advantage.
