Just wondering going from a Stock LT1 and putting long tube headers on it what kind of power increase have you gotten and or shaved off your ET ???? Thanks

Headers usually result in (on average) around a 15-20HP/15-20TQ increase when mated to a decent-flowing cat-back - more if you have additional supporting modifications (CAI, 1.6 rockers, valvetrain work, etc.). Those numbers in a perfect world would result in anywhere from .1 to .3 ET reduction.

Expect about a 22 horsepower increase and a track time of 13.7-13.9, don't forget to get it tunes and keep you spark plug wires away from the headers.
