On your deal using the good heads and intake you have there is no way I would put a small CFM carb., less than 750 CFM on it to choke it down tsk
I have play with, built and race BB Mopars since the early 1970s, every BB that is a RB motors liked bigger carbs, 850 to six pack to a tunnel ram with dual 750 CFM and so on up
Your right foot controls how much air goes through the motor at anything less than wide open throttle , correct work
The carb. size controls how much air and fuel goes through the motor at wide open throttle work
Take a look at Quick fuel, Holley as well as the other carb makers out there scope Not just Edelbrock down
I and a lot others on here have had excellent results using the Holley 950 HP carbs. scope
Little carb, little power, big carb, big power grinshruggy
