Ok I have a 04 cavalier I race dirt track with so far I have balance shaft delete, 2.4 intake, .020 head gasket, exhaust, I'm taking the head off this week and getting it ported polished and flowed so while I'm there I'm looking at cams to put in. Of course the motor is supposed to remain (stock) so I need ideas for a decent cam that has a decent idle and performs well at 4500 to 7500 thanks in advance guys. And yes it will be getting tuned and I have cobalt injectors to put on it. Thanks guys
