Can you tell me what's the difference between a LS2 and a L77? HP? Cam profile? Comp. Ratio?
Thanks

I have the part number:
19302121
It's a warranty crate engine, but no one has been able to tell me anything about it, other than it's a 6.0, it has cathedral port heads 799. I can't find info on the comp ratio or the cam profile. I'm trying to find out whether this is an equal replacement for what I had.
Thanks everyone for the input, it's greatly appreciated

That's everything I wanted to know. An education is for those who seek it. I appreciate your efforts, support, and attention to my matter.
It has blue springs (not yellow) on it so I know I can't twist it to make power.
Good Looking Out... Much Respect!
