Carter, Edelbrock, or Holley?

Greetings,

I am finally returning to my project after an extended period of unemployment. It is a ’73 Plymouth Gold Duster resto-mod. Power plant is a warmed over ’99 5.2L Magnum. Block is bored over 0.03” with a higher duration cam (duration @ 0.05 216 intake/224 exhaust), hypereutectic pistons, heavier (LS1) valve springs, and double timing chain, but otherwise stock. Goal is right around 290-300hp.

Intake is an Edelbrock RPM Air-Gap (7577) manifold. I would like to run a Thermoquad but have heard they are not compatible with this intake. The Edelbrock guys suggest a 1407 (manual choke) or 1411 (electric choke) 750 cfm carb. I have also looked into the base 600 cfm Summit Racing carb or a smaller Holley (4160 or similar).

My question is this: What carb would best complement this intake? I have been advised to try and stay within a range of 600-700 cfm. This is a low budget build so high-end or exotic carbs are not doable.

Thanks for any and all opinions.
