Eljaro-
I am running a TKO II with a 3.31 rear and it is great. first is short, but still very usable and 5th is a dream. At 75 the engine is turning about 2600 rpm. I wouldn't worry too much about the drop from 1st to 2nd or 2nd to 3rd, these motors have so much torque that it doesn't matter. Also, you need to consider the power curve for your cam when deciding whether to swap trannies or rear gears. With my current cam, the rpm range is 2500-6500 and I think a 3.54 rear would be perfect for it, even with the TKO II. I may wind up going to a smaller cam, in which case, the 3.31 and TKO II will be perfect, IMO.
