i was just looking up some info on the ls2 engine, researching a cam. hold sh!t, gm high tech put a livernoise stage on cam in and had it on the engine dyno, with stock gm tune it kicked out 90hp. thats ridiculous. i think im putting in a cam before anything else. the headers will still go on but they are gonna wait. i think its gonna go : install what i have now e-fans, tune, then cam it then get the trans ready real quick before it explodes like every other gm product i've owned has done. then headers i think I've decided to get a nice set of headers with high flow cats, because emissions testing is coming here in the next two years or so they say. and then i wont feel guilty about dumping junk into the environment.
