    Is your 2500HD 4wd or 2wd?
  • saddaddysaddaddy Posts: 566
    My dad originally planned to buy a new 1/2 ton 4wd, but then saw that a certain HD was only $1500 more MSRP. He asked me if I knew much about the 6.0L engine in it and I didn't know much. I told him that it was not anemic by any means. He also wanted to know mileage values. Thanx ahead of time.

    270hp?

    thats not a large engine.

    I have the 6.0L w/3.73 rear in my 2500LD (8600 lb.) 2001 EXT cab, short bed, 4WD, Auto, GMC. It is a great engine, although I do have the "knock" or "tick" on start-up. I have not been concerned about this and have not even asked for the extended warranty that GM is offering. I get about 12-13 MPG locally, and 16-17 on the highway at 70MPH in flat land. It and the 4L80E auto are a great combination....very smooth power. 300 ponies in mine, and plenty left at 60MPH+ to set you back in your seat. If you are at all familiar with the old GM 5.7(stock), the 6.0L seems much more powerful and responsive to me. I would recommend the 4.10 rear in a HD.

    That is some very helpful information. His current truck is a '90 GMC with the 5.7, so he'll like to hear that about the power. His current truck has about 120k and burns oil very bad, and has very bad valve chatter. He said that they are offering $2000 rebate on the 1/2 tons now and will probably get the HD if that rebate is also on that truck - not sure about that, though. He does lots of towing but nothing that would require the HD, but he will surely find something heavy to yank around. Any more pointer would be great. Thanx again!

    BTW, saw you asked about the GM engine knock in another topic. Here is my take on that for what it is worth:
    I don't know how wide spread the "knocking" problem is. I believe it is pretty common in the 6.0L, 5.3L, and less so in the 8.1L. Don't know that I have heard of it at all in the 4.8L, but I could be wrong. There are all kinds of opinions about whether this is something to be concerned about or not. My 6.0L "ticks" for about 45 seconds when you first start it after sitting overnight. I use Mobil 1 and have since 500 miles new. I would never have known the sound everyone is upset about was a problem, if I hadn't read it on this board. You do not hear the noise unless you are out of the truck, or have you window rolled down and are listening for it, at least in my case. There are people who already have 50,000+ miles on "knocking" engines with no serious problems developing. I have not seen ANY reported failures from this problem, even though it has been around since the new engines where introduced in (I think) 1999. Guys that know a lot more about engines than me are very upset, but I figure GM will stand behind their product if this does cause any serious damage. Haven't heard one single example of an engine being torn down and exhibiting damage from this. Wouldn't you think that would have been done by now if this was causing damage? Just my $.02 worth.

    What are you trying to prove?

    The I6 would be a desirable engine to a lot of Silverado buyers. I would be interested in such a configuration.

    There is really no point in arguing this. You're comment about it never being an option is not valid.

    Why not leave it alone?

    And, has anyone heard about this being considered?
  • ryanbabryanbab Posts: 7,240
    Have you ever heard of a chevy Crewcab with a smaller than the bigger V-8 engine (2500 series) offered?

    I could see the new I6 in an ext cab (maybe this is what you are talking about) but never a crewcab

    I have an '01 Chevy 2500HD 4X4 EC 6.0/4.10. I am an old Ford guy and I have to admit that, so far, this is one awesome truck. I have put 285/75/16 Cooper STT mud tires on 16x8 American Racing wheels. This is the only mod that I have done to the truck so far. I have approximately 14,000 miles on the truck. It pulls 7000 pounds with little effort (and stops it good too). It accelerates like a sports car and would probably outrun many of them if it didn't have a 97 mph speed limiter. I get about 13 mpg in mixed driving and I have developed a lead foot driving this beast. My engine has the cold start ticking or knock (whatever you want to call it) and has since about 7,000 miles. GM gave me a 5-year/100K extended warranty on the engine and all internal engine components by just asking (and having the dealer confirm the knock). I don't claim to know a lot about engines, but it doesn't seem to be a big deal to me. If you rev the engine slightly, the knock disappears immediately like there is not enough oil at the top of the engine when first started. My buddy has a '97 1/2-ton with the old 5.7. It has had the same knock since about 3,000 miles. He is pretty hard on his trucks and doesn't follow the scheduled maintenance as he should (coming back from the Texas race last year, the "check engine soon" light came on while I was driving and I asked him what he wanted to do - his response: "it says check engine soon, not now!"). His truck has over 90,000 miles on it now and still doesn't use any oil (and its still knockin' and still rockin'). Take it for what its worth, but I would buy another one today if I had it to do all over again.

    Look, I know you are a pickup owner.

    You are probably an expert at this point in aftermarket bed covers.

    You don't know jack about what GM is planning regarding engine options.

    I understand that, in your opinion, they will nor put an I6 in a Crew Cab.

    Thank you for that opinion.

    My question to anyone who may be actually infomed is whether or not they have heard of any plans to put an I6 in the Crew Cab?
  • saddaddysaddaddy Posts: 566
    That helps alot, man. Thanx. My dad's '90 5.7 has a bad valve chatter, and thats why hes getting rid of it. He thinks its about to give up the ghost. Basically what I have heard is that the knock in the new ones is THERE but, it seems to do no harm to the engine. I take this as good news and really wouldn't let it weigh heavily into my decision. Anyways, thats what I'll tell him.

    thanks for the respect delrick

    Shows what kinda person you really are

    Personally I wouldn't want it.
    My wife has the trailblazer and for the smallish
    SUV's it is great. But the way I see it, rated at 22 mpg, Yeah right.
    Just look in the SUV forum here and you will see many owners
    of the GM triplets (Envoy, Trailblazer, Bravada) that
    complain that they doo not see even close to the
    estimated MPG. We have yet to see it.
    What I would like to see is the upcoming 5.3. This
    one is going to be aluminum heads on an aluminum block.
    Don't get me wrong the I6 runs like a raped ape.
    but it does not have the torque.

    Just my .02 cents.

    'Ryanbob' has been posting informed, factual information about the I6 and the I5 since before you appeared. If you knew 'jack', perhaps you would already have the answer?
  • rayt2rayt2 Posts: 1,208
    When you did the wheel/tire mods did have dealer update computer for the configuration? Hypertech unit? or just let it be?
    I'd like to add different wheels/tires but concerned about mess'in up the works, these new computers can be cantakerous when you wander beyond their limits and the electronics field is not my cup of tea. Give me the 60's/70's cars anyday, those I can figure out.

    Your buddies interpretation of the "Service Engine Soon" light is a ripper, I'm still laugh'in.

    You got any pic's of the truck posted anywhere with the wheels?

    So far I have not updated the computer for the tire size change. Was considering getting a Hypertech and didn't want to waste the money at the dealership. I did get a speeding ticket coming back from the tire shop (75 in a 55 according to Ol' Smoky - but I swear the speedo said 62 when I saw him and looked down). I have since tried to stay at the speed limit or slightly under (most of the time). I clocked running beside the wife's Explorer - she showed 65 to my 60 which seems pretty reasonable to me.

    I really haven't noticed much, if any, difference in the power, acceleration, braking or anything else due to the larger tires (although the mpg has dropped from 13 to 12, but that should be basically the difference in the speedo).

    I don't have any pics posted anywhere, but if I can come across a digital camera and can figure out how to do it, I will post some pics and let you know.

    Even though you're looking at $350 or so, the Hypertech programmer appears to be worth it. Fixes the speedo/odo problem, lets you adjust for fuel, firm up the shifts, other stuff. Beyond that, after I changed tire size and before the reprogram, everything felt just kinda "not right"; shift points, braking, etc. The other interesting thing, as I think I said on a different forum, is that when I reprogramed back to low octane for economy during vacation in the flatlands, the throttle response and overall driveability then felt "off". I've gotten pretty much to the point where I just leave the hy-po programming in place and spring for the 25% premium for high octane fuel no matter where I am or what I'm doing. Costs more, feels better; at least for me.
