Speed, torque, r/a ratio, tire sizes

Thanks, Kieth!

I have some extended family medical stuff to deal with this weekend, but maybe we could arrange a call next week...

In the meantime, here is what I am planning on:

383 Chevy
Dynamic Compression = 8.02; Static Compression = 10.00 (Plan on running on 91+ gas)
Roller Cam: 232/242 @ .050; .507/.507 Lift; LSA = 112, installed 4 degrees advanced = 108 LSA (Wanting to start making power around 1500- 2000 to 6000)
Vortec Heads (Intake cleaned up; exhaust ported and polished; 1.45 springs good for .58-.60 lift; screw in studs)
Edelbrock Air Gap Intake
Looking for around 450-475 lb/ft at the engine

Transmission
TKO 600 with the .64 overdrive

Final Drive = 3.73

Tires = ? I have something like 245-75/15's on there now. I plan on buying new wheels and tires, but first I am going to see how this combo drives and then adjust my wheel size up/down to improve power/rpm at cruising speed (approximately 65-75 mph).
