LT1 vs LT4

:( What are the differences between the LT1 and the LT4? Can you put the LT4 heads on an LT1. I also hear alot of talk about using LT4 knock modules on LT1's for better performance.

LT4 have better heads, intake, cam, 1.6RR, and it has a four bolt main. You can use LT4 head, intake, ect. on an LT1 no problem.

Because the LT4 have noiser, higher lift 1.6RR, louder true dual exhaust (since it came in Vettes) The LT4 KM is decentised from the LT1 KM. So the LT4 wont pick up valve train, or exhaust noise an knock and pull timing.

Thanks for the info. You've been alot of help since I started and I appreciate it.
