From a race standpoint:

That is a tiny cam for a stroker and the low end torque will be beyond massive with the small ports of the stealth heads /750 carb.
--It will peak early and low.

That cam/carb combo would make for a very torquey, rip you neck off, street car.

Drivetrain:
- That 741 pumpkin will die a fast, horrible death with that motor.

- You will break that 8 3/4 at the weight you are pushing around. 4400lbs

- Don't put any money into a 8 3/4 for your application.

- Sell all the 8 3/4 parts before they are busted.

Also remember, when you bust a rear end it usually wounds the trans.

Before you start breaking parts...just buy a Dana.
It will save you the pesky future expense of buying a Dana, a new transmission and possibly your feet/life.
