I've got over 2000 miles on my TKO-600 and have not had any problems with the transmission. I went with the 2.87 first gear, the 0.64 5th, and a 3.54 rear. It has been a good combination. I'm running a 289 stroked to 331 putting out approx 390 HP (flywheel) at 6100 rpm.65 mph at approx 1700 rpm and I've still got good low end power for passing.

I'm glad that I went with the 0.64 for highway cruising (20.8 mpg), but if I had it to do over again, I'd probably opt for 3.77 gears for more power in 5th.
