I'm looking at getting a set of cams this winter, and just wondering what to get. My car is a DD. My current mods are PI H/C/I, C@L upper intake w/75mm t/b, pullies, shorty headers, x-pipe w/cats, SLP LM 2, 3.73's, aluminum d/s and flywheel, and SCT Xcal 2 tune. I want the max hp I can get without swapping in new valve springs. I was looking at Hitech stg 2's, but it looks like they aren't going to fit without grinding down the valves? So what cams are PI swap people using?
