Emissions Question
I am looking to add some power mods to the 99 vette in early spring next year.
Was interested in finding out if anyone has a cam/head combo that will not go over emission limits.
I am located in Canada and think we are less strict then Cali?
Anyone know of a combo that is offered for the LS1?
I have Callaway Intake, Kooks 1 3/4 long tubes headers, Kooks catt'd Xover (Random cats?) and Corsa Exhaust.
Thanks for the input, good or bad.

Try Cartek in NJ.

I have Stage 4X heads and 3X cam. No emission issues in PA.
It is a great combination with 4.10 gears.
Good luck!

Check out my profile and signature for all my mods--basically a hds/ cam A4 car in calif and it's smog legal--380-390 RWHP---About the biggest you can go and be legal is about .224/.224 @ 50---lift doesn't matter much but i'd keep it under .560 to make it live---LSA can't be lower than 114 (I've never seen a 112 pass but it's possible but i wasn't willing to gamble)--also i used Stock LS6 (243) heads with comp 918 springs that i mildly ported myself--

Thanks guys, will check the links and information out.
If I cannot find a cam/head combo that works was looking at just
swapping out the heads with AFR 205cc units and then 1.7 Scorpion
rockers and keep the OEM cam?
I saw this artical on a straight head swap on a almost stock car in
GM HighTech Mag.
They supposedly got 37hp out of just the heads on a stock 99 LS1.
Could just do the heads and rockers and with my Kooks setup should
put down some decent numbers, what do you think?
Also does that just head swap make sense with an OEM cam still installed?
