Im doing a t5 rebuild and swap right now. the first t-5 i got did not have the best ratios so I found another one better suited. the second one I bought has the 3.78 1st and the .72 OD. For now im going to run that with the 3.73 rear just for a bit then might switch the rear to a 3.42 mid summer.
The .72 OD with the 3.73 rear will take the 60mph at 3200rpm ish and lower that to about 2250 ish
would like to find a 3.50 or 3.35 first ratio trans then i could keep the 3.73 rear and not have a granny gear issue when starting out
