I got a Abruzzi 3 fiddy trans in my street car today and it works fine - going 6.51 1/8 mile and holding up fine - but if I should upgrade one day it could be good to go on a diet and go faster.
I have always built my own 400, its been one area in racing I have been able to save money in........so my current trans is all stk minus a billet forward hub, 36 element sprag, aftermarket clutches and steeks and a couple roller bearings
