looking for some info on what i would need to do for this, never really dealt too much with diesel engines other than the normal maintenance that gets done on my work truck it would be going in a 2008 sierra denali figured it would be pretty cool and different not to mention if i could get a 2001-2006 i wouldn't need to deal with the new dpf bull *** the lmm has that i keep reading about. any ideas for me or comments that i could use 4 help thanks

..also figure since i have the engine out i could go ahead and do some performance things to it in advance before i put it in my truck like a stronger set of head studs for a larger turbo setup possibly a twin turbo setup Aurora 5000 n maybe a 3000 in parallel? not so sure on details just a thought for now, anything else u think i would need besides a stronger tranny chip air intake exhaust and bigger fuel injectors for this engine to be a torque monster  

another thing i would like to know is wut u guys think this would cost price wise  

Figure the engine & trans combo will probably run $12,000, at least. I'd go with the LBZ. To be totally honest with you, I think it might be easier to start with a Sierra 2500, and do a Denali trim upgrade on in, than to start with a 1500 chassis and try to upgrade it.

For a gasser, the Sierra Denali is a pretty sweet truck to begin with. If it were me, I'd probably slap a Magnacharger on it and be done.

Just realize you're going to be dropping a ton of money on it if you're trying to swap a Duramax into a 1500 Sierra Denali. But if you've got the dough, go for it!    

I do have a fair amount of money to drop in it, but i thought the main difference with the 2500 and 1500 was the suspension system the axles i am not 100% sure on that tho maybe a stronger frame too? like i said idk for sure  

Yeah, 2500 and 3500 have totally different frames and suspension than the 1500. Also...I just thought of this, I think the Sierra Denali has a 5.5' bed, whereas a CC Short-Bed 2500 would have the full 6.5' bed. So even if you do get a 2500 frame/chassis, you'll probably have to cut it down.

Again, not trying to discourage you, but it's probably not exactly going to be a cakewalk.  

haha not discouraging at all my pops does have a old '93 2500 just sitting around if i really am having a hard time finding everything i need for the right price, also i was just thinking if the 6.6 is too big isn't the new smaller duramax engine going in the 1500 series of the sierra truck or did i just read it wrong as a wish not a reality  

Yep, the 4500 Duramax is a sure thing for 2010. Don't know if GMC is going to offer it in the Denali trim, but they'd be dumb not to. It's going to have 310 hp and 520 lb./ft. right out of the box, which is pretty darned good for a half-ton if you ask me.

In terms of performance parts, it usually takes the aftermarket about 6-12 months to come out with decent parts for a new engine. But keep in mind that all the 2010 diesels, whether they're half-ton or 3/4 or 1-ton, are going to have a ton of emissions crap on them. So if you're looking for "easy" get an '07 or earlier diesel.
