Which tires? Roughly 22" diameter? I generally used a 3.89 there, but it's an
awful lot of revs for a long time if you have no overdrive. I tried a 3.27
once, but the Spit didin't have enough grunt to pull that gear, and I was
drag-limited to about 88 mph. Not ideal either. Maybe the GT6's additional
torque would make the 3.27 gear work just fine.
I will try to remember to send you a gear calculation spreadsheet which I have
on my computer at work...

Need advice on which diff to run at Elkhart. Our first time out. GT6 with mild
motor. We have two diffs. 3:89 welded and 3:26 stock rebuild. Rev limiter set
at 6,000.
Thanks
