How much power?
I have a '90 RS w/ a 305 TBI and a 5 spd. My question is how many ponies it will hold up to and for how long. Thanks

Axle/Gears: precision 3.73's, auburn diff
if you baby it, maybe 350 rwhp. if you flog it, it'll barely hold up to the stock power.

thanks for the reply. i was told a rear diff. out of a 91-92 Z-28 would be my best/ reliable bet. if so does anyone have one?
