Thanks Guys... Please Help me out on this one :flag

Take a look at my mods in the signature.

My 12.93 was in excellent air, but the car can pull 13.1's all day.

Kevin

I am in East Meadow. I usually hit the track at Westhampton, do you go there ?

DR's and a Torque convertor will knock about 4 tenths off your ET.

Mini-ram, CC-306 cam, new valve springs, full length headers, and 3.73 gears will put you at low to upper 12s (depends on you).

If you open up the stock intake, put a high lift/short duraton cam in, headers, and 3.73 gears, you'll hit the occasional high 12.

You'll need DRs in both occasions. Changing the heads on both motors would provide definately more power if you match the flow numbers up with the cam and intakes.
