jwd,
Yes, it gets better with time. The best ones are trannys that have about 3000-10,000 miles on them--assuming they were not abused. The shift like butter.
That said, don't let ANYONE talk you into the stupid 0.64 overdrive in the TKO 600. It is a boat anchor. 5th gear is useless. Generally speaking, (in our cars at least) the 427 guys run 3.42 gears and the small block guys with big cajones run 3.54's and the small block guys with small huevos run the 3.73's.
Anthony,
It is true you can run the gear options you mentioned--that is what we used to do. I have run all of the gear ratios you mentioned (and even more) until we settled on the above combinations for the majority of our customers. Now, there will always be exceptions. Morris wants to run 4.10's in his car with a 5 speed. I think he is crazy. BUT, if you saw how fast he drove, you'd think I was the one who was crazy. I am sure the BATF will regulate him pretty soon.
Good thing everyone has their own opinion as it would be pretty boring if we all liked vanilla. Everyone has their opinion and that is what makes the world go around!
