Ok buddy at work has a 93 z28, hes putting a comp cam(not sure which size, he says one of the biggest ones) new lifters, roller rockers, port and polished heads and intake, cold air induction, 4.10 gears, torque converter not sure on the stall probably 3000, and a rebuilt tranny. I was wondering if anyone has an idea on what he going to run so I know what I need to do to keep up.

and his car has over 100,000 miles on it and when it took it to the track when he first got it he ran a 14.7 and it was pretty much stock then. thanks

 

hard to say without some more info find out what cam heads and stall gear tires and such I would say atleast 12.80's with the info you gave us but who knows

 

Bf Goodrich drag radials, definately 4.10 gears, 230 / 244, .510 / .540 112 LSA, as far as the stall goes, he doesnt have one yet but hes talking 2500 or 3000, I dont know how much of a difference there is between the two, Ive never owned a automatic.
