9.502 @ 144.32mph with a soft 1.451 60' is about what it did the first time out. had 95 jets in the 4500 and locked 28' of timing.....soft 2500rpm launch and 7400 in the lights..

getting my NHRA license and then down for the winter for paint. Winter upgrades......restalled converter,(PTC says mine is 4-500rpm tight), WCCH port match intake(stock as cast currently)...and we will start from where I left off come March of 2014

Sorry guys....just saw responses..and a bit of a update..new best

1.308 60' (4800 launch in 2step)
9.364 @ 145.47
5.909 @ 117.94 (1/8th)
7500 rpm in traps
13.6-1 cr
Sunoco 112
Swapped the Holley for a Mast single plane and had the converter restalled

2 weekends ago I raced a 9.60 index class and had 10 turns in the throttle stop(manual disk style)and ran a 9.602 and a 9.611. The 1.30' time was with 6 turns in the TS, not knowing where to start. The 10 turns short time was 1.351 60'

Camaro only weighs 2500 with me in it so all of this doesn't matter since I'm not full weight.
