727 rebuild stock/hp street
I rebuilt mine to run behind a mildly built 340. I was having the same dilemma as you are now. In the end, after much input from other members here who's opinions I respect, I did exactly what
@transman suggests.
I did upgrade to a 4 disc clutch drum, a 3.8 band apply lever, upgraded bellville spring and went from 9 to 12 clutch springs.......And a Transgo-1.
We'll see how she works.....Good luck.
