Alright, i got a 5.3(tr224) in my 87 camaro its almost done just waiting for harness to come in, and will be putting nitrous kit on it(150shot) with window switch, and my buddy said to put my spark plug gap at 0.045 for the N20, and i didnt know if that would be good enough or not? please let me know and the plugs are NGK TR55
