Hi, I have just about finished my 71 Mach restomod project. Its has a Fuel injected 347 with complete BBK intake setup, Powerdyne Supercharger and built
C4 trans with shft kit and hammer shifter. Now I need some advice on what to do with the rearend. I hit the gas 1/4 throttle and its one wheel wonder time with no traction at all. I want 3.73 so I keep some drivabilty. Which rearend is in there stock and can I build off that. any help would be great.

Thanks, Jesse

If it came with a 302 originally then its an 8". Unless someone swapped in the 9.
Although Im not sure any mach 1's came with a 302 though.
Here's more info on how to idetify what you got: http://www.kevinstang.com/Ninecase.htm

I believe only the 351's or better came with 9" rears.
