If you could build an engine any way you wanted to

I'd like to build several different 427 CID variation with the same carburetor, camshaft duration @.050, header diameter, etc. and compare them on a Dyno. That's a very attainable displacement for many engine groups and you'd have your standard BBC 427, a conventional 427 SBC, an LS-style 427, and even a 409-W-style 427 CID. I'd have to say that the LS engine would probably win but it would be interesting to compare.
