What kind of HP is the car putting out. How much does it weigh?

 

The car makes a little over 350 HP. It weighs 3700 lbs.

 

Joseph, looking at your setup I see you have stock heads. Did you have them ported and or a three angle valve job done? If not, I would tend to think they will be hurting your times some what with the ZZ-9 cam. With that said and assuming the heads are untouched, I would guess 13.5 at normal track conditions. But as I said, this is just a guess.

------------------
91 GTA 350 TPI. Edelbrock base,ported plenum with stock runners, TB airfoil, AFPR, relocated MAT, stock heads hand ported, TES headers, Flowmaster Cat back, Hypertech chip and underdrives. Best 1/8 mile run is a 8.74 at 79MPH. Best 1/4 mile run is a 13.77 at 99MPH.

 

The ET will really rely on how good your traction is. If you have 350 HP at the drive tires then you should run about 12.7's. If the engine is 350 hp then I'd guess 13.4's.
