4/7 swap in firing order..

That 427 FE definitely sounded different than a Mopar but I think it sounded kind of weak. It was a little smoother than other V8s when the guy in the video raised the revs for a couple seconds but it was a lot quieter and didn't have that same booming "cannon"-type sound that Mopars have. Hell, my mild 318 with the exhaust unhooked was nastier sounding than that thing (even though the 427 obviously had a cam).

My neighbor's 351C '70 Mach 1 sounds pretty beefy though, and I know that thing is pretty quick (geared too tall though).
