I will be running about 470 HP in my 454 (Flywheel HP) so i have been trying to find a decent manual tranny that will hold. I also want to determine what RPM is good to cruise at, (being I have lots of cam).

sounds crazy but i am trying to get the best of both worlds, I want it to be a tough street machine, but also have an over drive gear so it will see pleanty of use on the hiway.
