hello Im not sure what to do to my motor to get it to run in the high 12s. i got a 2000 chevy ex cab 5.3 i want to get a cam, headers, exhaust, and some other lil bolt ons but not sure what to get. later down the road i want to get a pro charger thanks for any input

 

I would say some nitrous a custom tune and some gears.

 

We both have the same truck...

My best so far is a 13.1 but it was 100* outside to boot.

Any forced induction will get you there.
But remember you got to take care of the transmission and other stuff.
