We have a 69 Camaro 427/425. We've run it since 2007, it's apart right now. Yes, it has GM replacement cylinder heads and intake. No, it is NOT a damned crate motor. You calling it one, with your ignorant opinion, doesn't make it one, either. It uses a a couple of GM replacement parts, but it is the original combination sold in 1969, a 427/425HP L-72.

Are the original L-72 closed chamber heads an open chamber 119cc replacement head cut down to 103.3 cc closed chamber specs?

Just more proof of how F'd up stock and SS are at this point
