BTW the advantage of the bigger BS block is you can run a bigger valve with more room from the bore, a hemi solves this problem.
Seems someone would come up with a race style Hemi head, ditch the "real hemi" chamber for a shallower one like the genIII with a couple quench pads so you don't need 500 pound pistons to get compression. Then you can beat em with a 4.8 BS while they are all trying to run a "wedge" that ain't a real wedge either. Look at the apache head, giant valve with big flow that still fits on a 3.91 bore for inspiration, no massive dome required. Scale it up and make it fit the 605" and let it eat. Too many mopar guys in the top classes trying to prove they can do it with a wedge.
Agree, a scaled up genIII hemi style head for BB would be amazing.

Actually the "stupid wedge heads" had something to do with the comparison, at least in stock bodied muscle cars on the street (which is the only place this comparison existed - racers knew better).
The smaller port volumes of wedge heads made much better low speed torque, which allowed the mild cammed 440's to better cope with the heavy weight/low stall speed/street gear ratios that most muscle cars had. 14 cubic inches certainly helped, but that alone wasn't what made the two competitive.
It was the fact that the stock street hemi was mismatched and out of its element in mild low speed street driving, and the 440 wedge was nearly perfect for it.
