According to the dyno work I have watched, you would still be overcarburetted with two 450's. The 390 CFM's have been around forever. We used to run ONE 390 on our 400 CID Chevy Sportsman road race car (those were the rules). They made over 500 HP with one 390 carb.

A 390 lower-compression cruiser needs about 650 CFM total.
