Hey Im working on my 97 trans aml t1 and I am looking to put new headers and a cam in it. I'm not sure what cam I want to put in it. I want something more aggressive than stock but not something crazy. I'm still in high school so I cant dump to much money into it besides a cam and headers. I have heard good things about the 503 but I have also heard bad things about it. What do you guys suggest for someone not planning to do much else besides put a cam into it?
