I'm totally with you on the Dominator carb criusing down the freeway in 65mph on fifth gear not gonna work. If going the carb. route would Indy 4150 flange 400-2 max wedge intake with a good Wilson port job and a Quick Fuel 880cfm vacuum secondary carb. be a restriction that will hurt the air flow so 700-750HP is no longer in reach?
I don't think you'll get anywhere close to 750 hp with an 880 cfm vacuum secondary carb. You need ~1100 cfm for a 512 at 7000 rpm, and you're going to need that kind of rpm to make your power goal.
