We all know an engine is just an air compressor right? Look at those 426 Hemi intake ports, then at your wedge ports (max wedge ports if that makes you happy), Tell me which one is going to pump the most air through them.
I don't know any street racer back then that just kept adding camshaft to his 440 and went faster and faster. But that's what works in a 426 Hemi (and big block Chevy for that matter).
