Quote: I installed a 274 ist 1.55 second gear set in my 727 (the gear set changes first and second) gained a tenth in the quarter aint cheap. stock gears are 2.45 1st and 1.45 second! definately a boost for heavy cars.
If you swap the 727 for a 277 geared 904 you can gain about 2 10ths.
Would it make a noticeable difference in a mostly street driven car? I see quite a few reply's about the gains in track time. I am actually considering a tranny that has a 3.06 first, 1.65 second, 1.0 third and a .7 O/D
