Which rear end do you have and will you primarily track the car or do a fair amount of highway driving? with a 3:54 or 3:77 rear the OD will be nice for highway driving at 80 mph and rpm's (without checking a calculator) in the 2200-2500 rpm range. On a track, 4th gear at 6000 rpm's will get you to 130 mph, so unless you're on a long straight, you won't use 5th very much. I am going with a tko600 and .63 OD for the highway benefit, witha 3.54 rear.
