A buddy has a 3.91 741 case center section that I am thinking about buying. I believe it is a small pinion, but not sure how to tell. The only issue is that it isn't a Sure-grip so I'll need to buy a True-Trac or something similar. My driveshaft is small pinion (both ends have a taper). The driveshaft fits with the 741. The current center section is out of a 58 or 59 8 3/4.
My question is if it's too small for the power I'm making. My 440 is dyno'd at 450 hp/538 lbs-ft. I have a 2400 stall and shift kit in the 727.
I don't know alot about rear ends, any advice helps.
