i have a 86 Z28 with the T-5 and i was wanting to know how much power can it hold hp wise with the mods i plan to do to the car iv herd the tranny wont hold up im not doing anything crazy, the most i would do is a built 350 so like 350hp
also is there a difference between the 85-86 iroc T-5s and mine, are thay stronger?
also what brand of clutch is best for these cars
and does anyone have a hurst shifter for sale i really didnt see one in the parts for sale
