the TKO I had with the .64OD was too much for me with 3.21 gears, and was just right with 4.56s. with a 6th gear OD in the .5x range I'd have to have run 4.88s!!

3.21s my 5th gear was lugging at 1800 rpm at 60mph and I had to get up to about 75mph to get the engine to smooth out.

4.56s was a smooth 2400 rpm at 75 mph. perfect!

that was with a 28" tire too, so a shorter tire will help out.
