Tunnel Ram Power Band?

I am building a 383 and would like to run a Tunnel Ram. What is the RPM operating range for the manifold, or what would be a good cam to run with it?

Engine is a 383 bored 30 over, stock stroke, 440 length rods, domed pistons with 1/16", 1/16", 3/16" ring set, 10.5:1 compression ratio, 906 head ported with Mopar templates, all backed by a 4 speed.

Its going into a street car.
