For a mostly raced car 4 speed - why because every now and then when going for 3rd gear I hit half way between 3rd and 5th. I haven't done it in a long while. Maybe I got better, but it still is in my mind.

For a mostly street car 5 speed - an hour of 3000 rpm and loud pipes is just no fun.

Get a TKO - 600 with the .82 5th gear. If you want a .64 then get a 6 speed. The step from 1.0 4th to .64 5th sucks. I know. I have one. 5th gear is useless unless I'm on a interstate, as the cam does not like 1500 rpm.
