I have an 84 Z28 that i rebuilt from the ground up. I has a 350 .060 over comp cam 540 intake 558 exhaust solid flat tappet 252/260 at .050 113 heads, ported with 1.6 exhaust valves, full roller rockers 1.5 ratio, 11 to 1 compression ratio, single plane proffesional products hurricane intake, 750 holley double pumper, shorty headers, cut outs, turn it 7200 rpm. World Class T5 with centerforce DF, 4.56 rear gears, has moser axles and all the goods so hopefully wont break. UMI adjustable torque arm with crossmember, and some 26 inch tall slicks. Car sure is a hell of a lot of fun on the street Would appreciate any suggestions also. Thanks

 

i'd say low 12's so long as the t5 and rear diff stay together

 

i don't see it making to the 330' marker with any real traction. t5 AND a 7.5" 10bolt with slicks and a stronger than stock clutch. something's gonna give, and i don't see it being the slicks OR the clutch.

 

Providing the tranny or diff don't fail, low 12's should be obtainable.

 

he has already gone 12.5 without launching spinning thru 1st w/ dr's
60' was 1.9
and mph was 112

 

Well he asked for opinions and we gave them. If you really want to know what a car will run in the 1/4 mile, you take it to the track. Guesses are just that, guesses. Don't be disappointed if performance isn't what you expect. Everyone thinks they have a 12, 11, 10 second car until they get a timeslip that says otherwise.

 

The key words to this is the no launch and spinning part....... This is what the guys are trying to say. Once the thing hooks maybe things will be better.... or maybe they will go BOOM
