I ran 12.99 with a custom cam and tf aluminum heads that are cnc milled. tf intake. probe pistons 10:8:1 compression. 373 gears on a micky tompson street radial tires. Everything on the car is aftermarket except for the block and the crank. In other words its a money pit lol!
My best so far with only one time at the track is 13.2 with the combo below but that is on stock gears so I know its a 12 sec car when I put in my 3.73 but 3.55 would get me there as well.
