what cam for emissions and power? so i have a few questions on what cam i would want to put in an ls1 m6, i have to pass emissions "sniffer in pipe and check for cats, egr, ect" i live in idaho and i dont think there is to many people that are able to tune the ls1s great so i cant puch it on the cam, with that said what would be a good street/strip cam that sounds mean but is still vary drivable and has a good idle!? i would do the normal bolt ons intake/exhaust, would like to do gears and i want to run my nx kit on it not sure what size yet 35-150! other then that im not sure what else i would do to it! so what do you all think?

Check your local forum, but I think he is right a TR224 on a 114 las is probably your best bet. A tune is also important. There should be someone local that does good tunning.

Meridian Id. You scared me man... I just moved to Meridian, and before I did I talked to a few smog tech's out here.
I JUST got stage 2.5 PRC 5.3L heads a 224 224 .581 .581 on a 112 comp cam, race style pacesetters, an LS6 intake without egr, pulley, oil pump, etc., etc.
So when I saw this post I drove down the road a mile or two to the somg station on Fairview and Locust Grove (literally)... and just as I'd been told earlier.... On any vehicle 96 or newer (OBD II) all they do for a smog check is plug their computer into yours.
This means, thanks to great tuning programs such as LS1 edit and HP tuners, you can do basically whatever you want
. You can edit your tune so you won't thow codes for things like egr delete, or not having cats. Since they don't do the sniffer test, you can run whatever cam you like (with a decent tune).
I think since you had a 92 (non-OBD II) pickup prior, they probably ran those test. Where did you get your smog info. Try talking to a tech at your local smog station.
