Wasnt sure where to post this but here we go! Sold my 04.5 cummins and am currently looking for a used duramax. My price range puts me in the 01-05 year trucks. My question is should I buy an LB7 or an LLY? I know each one has its quirks but am wondering in general which is the best option. Thanks!

lb7 has the obvious injector issues, lly has some cases of overheating and some headgasket issues. Personally I like the lly and newer trucks better than the lb7. The ability to use the VGT turbo as an exhaust brake makes them great if you are towing heavy. We have an 05 that is a shop truck/ work stock puller and has had the hell beat out of it without any problems.
Ok I like what I'm hearing. There's a guy in Denver here that's a dmax guru and he likes the LB7 (his has 1200 hp) lol. He said lly's have electrical gremlins and lb7,s have injector gremlins. But he said a fass helps the injectors and cp3 alot. I test drove a 04.5 lly today it had 113,000 on it but it ran great! Only problem was the previous owner was a smoker and the wife and I picked up on that immediately. I think I can get it for around $16,500-17,000. There's a few LB7's around here too though. Tough decision.
