have your cat fights there.

BMW has also been toying with the idea...
I'd also like to see here more mainstream light trucks from Europe. Unfortunately, until they get rid of the "chicken tax," it won't happen.
Bob
Toyota has been working on other trucks, that have been stemmed from the third world LandCruisers.
I'd like a LR pickup to set foot on US soil, too.
Ford....new F150 1997
Chevy....new Silverado 1999
Dodge....new Ram 2002.
A new vehicle takes alot of planning and $$$$$
So my question remains......if DOHC is so great for full size trucks why havent the big 3 gone with DOHC?
So my question remains: If pushrod/OHC engines are so great, as you imply, why can't you guys compare similar displacement engines to eachother?
I'm actually still waiting for your post you've claimed that I quoted you from.
Go back and READ my post, Jim. I stated the cost to operate and maintain is a reason. For mass production and fleet, it's cheaper.
FOr the engineers, it may be easier to build, and faster to build. 60 Ford F150's to 1 Lincoln Navigator sold a week. Think about it.
Loyalty is another reason. Most die hard truckers don't like their trucks to change, at ALL, for whatever reason.
Do I have to put a restraining order on you? I thought I said if that's not the reason you are looking, nag someone else.
Anyway truck guys don't like change, thats why the Silverado looks like it does, thats why it has pushrods in part. People that buy the SIlverado like it how it is.
yes I know styling plays a big part, it is the #1 reason people buy Impalas. I'm just saying magazine shouldn't rate cars on something that is very personal

"But I've read more statements from die hard Toyota lovers to the effect, that they wouldn't buy domestic even if it had more power, better fuel economy, better braking, cost less etc."
Hold on a minute where did you get this false info. I looked up the numbers from the Edmunds test on the trucks and found the opposite:
fuel economy observed was 14 mpg for the Tundra, 12.7 for the Chevy and 12.3 for the Ford.
Same for the braking from 60 to 0: Tundra=134 feet; F150=142 feet; Silverado=140 feet
Price: 32,339 for the Chevy, 31,880 for the Ford, and 29,548 for the Tundra
So in terms of price, fuel economy, and braking the Tundra is better. The only problem with the Tundra is the soft stock shocks. They are too soft. But get the TRD option package and your problem is solved. That is why it ranked third in the Edmunds comparo. They should have used the TRD option package on their test truck.
The Tundra is a great truck. It has better reliability and quality and refinement than the big three can offer. It did not becomes the number one pick by Consumer Reports and JD Power and associates by accident.
I have read most of the 1500 plus posts in the Silverado Problems thread and I am shocked by the lack of quality in chevy trucks. The problems are very serious: piston slap, oil consumption, shaking, electrical failures and the list goes on.
Why would someone ever buy a Chevy after reading this thread is beyond me?
They hooked 5000lb to the Tundra and the Whimperado, and they preferred the Tundra. The Tundra also got 3mpg better mileage while towing the same load. It just shows how weak the Chev 1/2 tons are.
Do you want brakes? The Tundra was loaded with 1350lb. and STILL outbroke the empty Whimperado.
They said that the Tundra was a better value, better off-road, better handling, etc., etc. You need to take those Chev blinders off and READ the article.
or maybe you missid this part about the tundra "the lack of bottom end frunt is evident when carrying heavly loads"
or maybe you missed the silverado beat the tundra in handling loaded, since it is actually made for what a pickup was invented for.
you could have missed "comparing apples to aplles, we'd say Toyota's payload rating is optimistic, while the Chevy's is pessimistic"
and they suggest getting helper springs if you are going to haul with the tundra, what a joke.
admit it the Tundra is made for people that want trucks to be cars, yes the tundra is more refined, its made for city driving, the silverado is is made for work. we have been arguing this same stupid crap for over a year. Tundra is made for the daily drivers who like cars, and the Silverado is made for truck guys.
Since i've been shopping around for a new truck i talked to many of these new truck owners about their trucks unfortunatly they ALL think they have the best truck in the world, getting any complaints out of them has been real tough. So far none of the Toyota drivers has had their truck in the shop for anything but routine maintenence. The Ford drivers have had a few small problems. Reliability seems to be going to the Toyota crowd though.
"This engine demonstrates the global nature of todays economy. All aluminum castings are imported from Japan, while all forged-steel and cast-iron components are imported from Germany. Connecting rods, crankshafts, cylinder heads, and cylinder blocks receive final machining and metal treatments at DMAX, where engine assembly and testing are performed."
You America-hater you, CTF.
hey bama no comment on the fact that you overread all the parts of the article that discount toyota as a truck?
Hey, I thought we sent you arch enemies over there.
A 4 valve head is superior no question if you want to make maximum power. Why do you think Indy race cars use DOHC? At the same time it consumes more fuel, look at any DOHC engine, they arent easy on gas.
tav I'll stick with talking about trucks instead of your wanting a man in your life, thats your problem.
It was a simple question, I'll try to give you the answer, the big 3 recently (1997 and later) introduced all new trucks. Theres alot of profit made from every truck sold, much more than almost any car with a few exceptions.
So you dont think that if the big 3 thought that DOHC was the way to go they would design DOHC engines for their new trucks?
Chevy brought out all new V8s for the Silverado in '99, if DOHC was the way to go they could've developed DOHC engines for their new full size trucks as easily as they developed OHV engines.
SOHC engines have one cam over each cylinder bay with opens and closes one intake valve and one exhaust valve. 2 valves per cylinder is what is associated with DOHC design.
OHV engines utilize pushrods to open and close the valves.
Despite all the mumbo-jumbo about DOHC being useless in a truck because they high-rev, Toyota's relatively small 4.7L DOHC produced 315 ft/lbs torque at ONLY 3400RPM. The Chevy 5.3 produces only 10ft/lbs more torque but at 4000RPM. You tell me which one has to high rev to get the torque.
I really don't care why the Big 3 haven't gone with DOHC. The Big 3 are still making trucks in today's day and age that can't be recommended by CR, JD Powers and Edmunds because of atrocious quality/reliability problems (you know, knocking engines, malfunctioning brakes, Fords with bad lug nuts having wheels fall off, interiors literally falling apart, Fords with slashed tires and roll-overs, the list goes on and on). I guess the real reason is that they're not progressive.
Personally, I think Chevy should learn how to fix the knocking problems on its archaic pushrod engines before they even think of attempting something more complex like DOHC. And I think others would just be happy if Chevy just made vehicles that didnt' have interiors that shaked and fell apart.
So your 5.3 produced the same torque at 3600RPM that the Toyota did at 3400RPM? Wow. Aren't you guys the ones who keep saying you want all your torque at the lowest RPM? Toyota beats again.
This is a totally ASANINE argument - you guys trying to compare your bigger engine to the Tundra's when you could and should be comparing your 4.8. I wonder how the Ranger guys would have reacted if I compared my 3.4L V6 Tacoma to their 3.0L V6 Ranger?
Come back here when you're willing to get REAL and compare the Chevy 4.8 to the Toyota 4.7.
amorales, the domestics have gotten quite expensive as well. My dad and I looked at all kinds of vehicles a few weeks ago and saw $36K Explorers, a $31K tiny Blazer that wasn't close to being loaded, etc. A decently equipped 4cyl Camry can be had for slightly more than a similarly equipped 6cyl Malibu. ALL vehicles, especially trucks, have gotten expensive - just a sign of the times, not one manufacturer's fault.
Happy Thanksgiving everyone (even pluto but not bama ) talk to you in a couple days
"Straight six (or eights) lost their appeal because "V-type" engines are easier to package. You don't have to have a long hood with a V-type engine.
Bob
It all boils down to who designed the engine. If you have a Japanese designed (Whether it is built there or not) engine like Quad, you have a chance of it lasting.
I wonder if the "next generation" truck V-8s will be DOHC? Or, will this new TrailBlazer engine replace the current V-6 and/or 4.8 V-8 in the Silverado? From what I've read about the TrailBlazer engine, it appears to be a better engine than either of those two.
Bob
Stick to the trucks and we'll be fine!

BTW, I couldn't find this bit of info on Motor Trend's web site; only in the magazine itself.

I'm sure if they decide to build a truck using the 4.0L (as a starting point), the engine will grow and it will be "truck-tuned." As I said before, if there's one thing Honda can do well—it's to build engines; and not just "screamers." Their off-road ATV and off-road motorcycle engines are perfectly suited to their respective tasks. The truck engine will also be well suited to the task at hand too.
MT used the word "full-size," but I know from past discussions with you Quad, your definition of full-size differs somewhat from what the manufacturers (at least Toyota) says. My guess is, if Honda decides to build a truck, it will be in the Tundra size range.

The reason for posting is that perhaps this would give a hint of what Honda has in mind for their pickup...
