what's next

The only way you are going to run with that stang is gears and some kind of power adder.

What are your cam specs,and compression ratio? What trans and gears are you running?

a stock 05 mustang GT three valve will run a 14.3 stock with ok street tires... thats gonna be a hard sell when you pull up with slicks lol....

but what do you do with the car?? mileage needed? street manners?
