Which camshaft, heads, ignition and gears really will help determine the answer. Without knowing your combo, I would put the smallest carbs you can get... even if you end up with 2 500 cfm Edelbrocks, that's 1000 cfm of flow, and that's probably too much.
Traditionally the tunnel ram will work the best at the high end of your RPM range, and will give up power/driveability at the low RPM's. IF you don't have a decent cam and fairly low gears, the tunnel ram would be better used for a boat anchor.
