Which edelbrock carburetors do i need to run this manifold on my 390? I think 2 450s should be plenty of fuel.

We normally suggest the 500 CFM carbs for this intake but the 450’s may work fine depending on if motor is stock, modified stock or if after market heads and crank(stroke) are being used.
