Default Cam optimal operating range

I would like anyone ,with the appropriate software, to plug in the numbers to give me the optimal operating rpm range of the cam listed below. I got the cam with the engine. I am ready to install the engine and want to purchase the correct torque convertor for the C6 with reverse shifting manual valve body.(I know I have already got static for an automatic tranny). The cam is a Crower solid roller.
The engine is a 427 CO with forged crank C5AE and lemans rods. the heads are L/R C3AE 0609 H with 219/177 stainless valves. Edelbrock Performer RPM manifold. Roller rockers. Arias 10-1 comp pistons. I hope this is enough info for proper calculations.

Thanks
Paul
