raced a lt1 trans am tonight in my abody!

did a 20roll and yeah i spin first gear! with 295/15/50 tires! my goal with this motor is to beat it until it blows lol im starting a 408 stoker build for the car this winter. my goal for that motor is 500whp. and im thinking about juice. i got a bottle and line. found a used kit for 200 in town. do like a 150 shot. id like to beat most people in my town(350hp) with this motor now. im guessing my at like 250 right now. so im thinking nos is the cheapest and fastest way for it. but can i do 410s with nos. or too much? keep the 323 with the nos.? is there a better intake i can run with that cam? stock heads right now. dont wanna do a head swap with this motor.
