your off the shelf cam choice is the CC 503 or cc305 or a custom grind.

my car fails horribly. i just have to find other means to get a sticker. I didn't let a sticker stop me from getting a little more hp.

no real tricks just a motor that runs right.must people dont realize that lt1s generally have a problem w/ nox which is a result of high combustion temps.the big cam relieves the temps.there is alot of exhaust reversion which helps co. but the test may not take the first time because of this. the new bigger cats will also get rid of the extra h/cs the cam produces.i have a egt so i can tell when the cats light off which is around 600 degrees .this test was done through a th350 w/4500 stall feel free to come check it out.i still have print out.i would recommend a pretest. i am not the only one to do it.your smog guy will need to help on the visual and a little pateints.

how far down is your cat?

i took mine off for now, but itll go back on after the Y pipe (like 12-18" before the rear end) so i doubt itll get hot enough.

both cats were about 6'' to 8'' after collectors.i would not recommend one cat when smogging a cammed car.although my partner barley passed w/ a hot cam and one cat.
