    The 6.2 will never be much of a dune runner. You need to get away from the nasty oil burner and get yourself a motor that'll run. The big block will easily outdo the 6.2 in every way (except fuel milage) and if it has some go fast goodies it should take you wherever you want to go and beat some of those loud obnoxious golf carts.

    I'd sell the 6.2 blazer and buy a gasser. I'm sure one of these oil burner guys would love to buy a factory diesel K5.

    i'd bet you've got 3.42's or 3.73. the biggest problem with the diesel set up is that they typically come with very poor gearing. that vehicle was designed solely for fuel economy, thus the high gears. before you put money into a turbo or a new engine, find a set of axels w/ 4.10 or 4.56 gears and then see how that truck performs - i bet you'll be surprised. ever thought of going to a manual transmission? that will increase the amount of power you feel significantly too. i've got a 6.2 w/ a manual and 4.10s on 35's, and it gets me up and going as fast as i'd ever want it to.

    edit. those numbers i listed out: 6.2/700/208 stand for 6.2L diesel engine/700r4 transmission (automatic w/ overdrive)/np208 transfercase. ;)

    IMHO diesels don't rev enough to be a really good dune runner. I think it would help a ton though if you got the banks sidewinder kit. I am a fan of diesels and would love one to wheel, but if it was mostly sand then I would have to say go with the gas motor.

    Yea, except in glamis there are some sick dodge diesels. But if your staying chevy, I would recomend a small block over a big block. That is alot of weight. I would also lighten your truck as much a possible. Big heavy trucks have a hard time going u olds hill. Put a small block in it, and 4.56 gears and keep the rpms up.Dan

    a BBC doesn't weigh that much more than a SBC, since you have one sitting around run it. As already said it may be worth selling your truck and getting a gasser if you don't have a lot tied up in you current rig

    I went the other way with my burb - 454 tbi to 6.5. But I added a blower instead of the turbo. With some careful consideration of parts, the 6.5 will make great power and torque. I have a 88 burb with a 6.5 and the banks kit (used to be a 6.2). Once up on boost, it really comes alive. But the banks turbo is a little loose, and takes some time to spool up. I'm planning on a different turbo with a waste gate in the future.
