Quote: Ouch. I get a little nervous with a 4 speed in front of an 8.75 that will see little track time after these posts.
I blew up an 8.75 behind a 340 , 4 speed in an A body with greasy B.F. Goodrich tires. There is a reason that Chrysler put out a TSB for the B body 8.75, 3.91 geared cars that came in with blown up rears to replace the 8 3/4 with a 4.10 Dana60 ...
But that has nothing to do with this subject, you can throw thousands of dollars at the 8.75, the weak link is the ring an pinion and there is noting you can do about that.
Monte is right, a series race car needs to go with the strongest rear, drop the big coin once or drop more till you finally get the rear you should have.
