James,
I'm not quite sure what *you* mean by top end performance, but if you go
with 3:27 rear end ratio you will have slower acceleration, and a lower
cruising RPM in all gears, including overdrive (and really, in my opinion,
too tall for the GT6 OD in 4th). The overall performance will match a non
overdrive GT6 with a stock 3:27 rear end ratio. With the 3:89 ratio as
fitted to *most* overdrive GT6's you will recover some acceleration
performance lost with the higher ratio (off the line in all gears) and have
almost the same (actually just a tad lower) cruising RPM in overdrive 4th
as a stock 3:27 ratio'd car in fourth -
