LS1 Information

[ItDoRun]

All,
A guy I go to church with asked me today if I was intersted in a 350 that came out of a 2000 or 2001 Camaro. Knowing that this guy knew nothing about cars, I was hesitant to even answer him until he told me it was $1,000. Supposedly, a gentleman he went to school with pulled this motor, ECM, wiring harness, etc. out of this Camaro and now has no use for it. I believe he will throw in the transmission too at no charge.

Now the question I have is how do I tell if it is definitely an LS1 other than the all aluminum block? Did GM make an aluminum 305? This almost seems too good to be true. It has to be blown because I don't have this kind of luck. What do I need to look for? Any help is much appreciated.

Thanks,
Chris
