Ok i have a 94 camaro A4 with the LT4 conversion kit on it and i got a mail order tune with hookers shorty headers and 52mm throttle body and 3.73 gear and 3200 stall and as of right now i run 12.80 at 107 on nittos but i want to run high 11s to 12.00 and i was going to go with the XE comp cam 230/236 and dyno tune but would that be worth doing or should i hit the TNT kit 150 shot but remember my rear end is stiill stock and my race weight is 3530 with me in it.

 

I can't believe your only runnin 12.80 with those mods... Try and run a few more times, if that doesn't do it, do n2o

 

Oh man!!!!
I can't believe it either, you should be breaking into really low 12's if not high 11's.
Definately, cam it out and dynotune it. You'll be in the low to mid 11's.

 

what were your 60's? How was the weather when you ran? Depending on the weather condition and traction, 12.8 may be about right for your setup.
