Chris, the TKO and TKO II (now the TKO500 & 600) are good strong trannys. Your choice will be determined by your rear end ratio. I run the TKO with 0.68 final drive with my 3.73 rear. To run the TKO 600 you have a choice of a .64 final or a .82 final. For all around fun from scratch I would use a 3.08 to 3.27 or so rear and the .82 final. This would make the 5th gear like just another gear. My 5th gear is an obvious over drive drop and my first gear is pretty darn high so on take-off I can barely make it across the street (3.27 first gear). Here are specs:
