I'm pretty sure that you are right with regards to both simplicity and power. Modern single four barrel setups flow very, very well (thanks, NASCAR), and provide all of the CFM's a high revving 302 would ever need.

The dead giveaway on Smokey's hemi heads is the exhaust port spacing. Rather than the two center ports on each side being virtually siamesed, they are evenly spaced, like on a big block, or on a Chrysler Hemi.

Yep, I'm aware of the Mopar 6 pack. And the "Tri-Power" GTOs are pretty legendary. My dad knew a guy that had a 427/435 '67 'vette with 3x2. They did take it to the strip. I remember my dad talking to me about tuning the carbs to get the best 1/4 runs when I was a kid. Chevy also put 3x2 on the 348 (predecessor of the 409). I think they went to 2x4 on the 409hp/409.
