Rebuild 904 or swap for 727?

Um, ok, you say .15...I already said 1/4...which is .25...you're condemning the swap LESS than I am. A 727 converter in a 904? Get real. Bolt in 727 sprags are about $150..."big benefit"?? If you're building a car for the track and you really really need that extra .15 of a second then you are not my customer. Go ahead and buy the $3k tranny; pay somebody to put it in; and might as well pay somebody to do everything else on your car; but not many on here can roll like that.
