I've driven Ls-6, l-72 and a l-88 vette and hate to say it but the r series 427 Ford would eat them if you could get it to hook up. How would the zl-1 hold up to the 67 427 R Ford. That would be in the league of a Zl-1 would it not.

Actually, an FoMoCo 427 is spec for spec pretty close to an L72...other than the 2-4 setup and the better exhaust manifolds on the FoMoCo, the technical specs are *very* similar. Brian Stefina and I have compared our 427s (he has a '63 425hp Galaxy) and it's almost like they came off the same drawing board, also performed *very* simliarly on the dyno...
