What's the best intake/carb for my build

1 of these 2;

Edelbrocks RPM Air Gap or not.

Wieands Action Plus

Using the stock Carb? Or in need of one?

Best throttle response and street manored carb wold be a 650 CFM carb and a 750 for street strip. The manufacturer of carb is your choice. Holley or Edelbrock, it's up to you.
I would use a vacuum secondary Holley carb. Or the AVS Edelbrock carb.

I would not use a Holley double pumper or an AFB.

And I agree, the stock intake and carb are fine parts and good for this application. Just not maximized. Inexpensive though!
