I know a guy that has a 2000 or 2001 3/4 ton Chevy pickup with a 5.7L. He said I could just have rge motor but I dont know if I really want it...what are the pos & neg of this motor & what is it called(what gen or LT?) Are theses considered vortec heads? Would this be a good option for a roller cam motor to replace my GenI 350?

Any other suggestions, maybe its just a boat anchor?

Thanks!

The 5.7L is a gen II motor. It would not be available in a year 2000 pickup. The new gen III engines were used in 2000 (4.8L, 5.3L, 6.0L, LS series).

Find out which engine it is, and what year the pickup is.

Either way, I'd take the engine for free. :yes: I'd pay good $$ for a gen III engine. :D

I agree, that should be an LS series engine. In the 3/4 ton, the base motor was the 6.0. I believe it's called an LQ9. Is there any way you can take a look at the build sheet? It should be in the glovebox.

I'll be near the engine again on Wednesday & I'll take a look at it. From what I understood the Gen III engines went in the Silverado(1500-3500) & the C2500 & C3500 in 00' still had the 5.7 or 7.4. I've run into that a lot in the aftermarket parts biz but I'm gonna double check it & let ya know, maybe he told me the wrong year too.

If it's a "WORK" truck using the old body style of pre 1998

The engine will be a 5.0 or 5.7 engine and will be vortec.
One piece rear main seal, 4 bolt, vortec head FI engine.

If it's a Silverado, it will have a 4.8 or 5.3 LS based.

You're right. They treated the trucks different from the Suburbans, too. The Suburban 2500 in 2000 has the LQ9 6.0l.
