I have the 3.54 rear gears with the 0.64 TKO 600 and it's been a good combination for my engine. That said if I had it to do all over again, I'd probably go with the same tranny and 3.77 gears. From what I've seen on other threads, if you want to convert to 0.82 you're better off to sell what you have now and buy a new transmission.
