51 your tire roll makes a difference if i ran a 650 on a 3/8 i'd turn 7200.

41 if your running a 6.50 on 1/3 then 6.20 or 33 would put you right around the same rpm on a 3/8

I run a 567 on a 3/8 and crank 5800. A friend of mine runs a 567 in his and he cranks 6300-6500.

I run a 3/8's medium bank track and my final gear is a 620 and turn 6000 rpm with about 87" roll out.

I ran 6.27 on the 3/8 medium banked 3 speed tranny in 2nd gear. Just picked up a Ford 9in for the new car and put a 6.33 in it to try with the glide. Eddie
