Re: Difference between 8.8 and 9 inch rear end

FuzzFace2
was there even a 5.03 R&P made?
That is not a top speed ratio even with over drive.
I think they made a 5.13 for the 9" rear axle, don't know if for the 8.8?
Any way to take a picture of the tag and post it up?

My drag car has 4.56 rear gear and 29" tall tires and at 1000' mark, 1/4 mile is 1320', it would run out of breath at 6000 RPM and 90 MPH.
A 4.10 gear would still get me off the line good but lower the RPM and raise the MPH at the 1320' mark.
But to change out the gears in an AMC axle is not fun so they stayed in.
