from what I've heard a cc305 or hotcam will pass emissions on stock heads. It also depends on where you get the car smogged. If you do out where I live (the high desert) they are less restrictive on things like emissions, in populated areas you'll have a tougher time. Good luck.

 

This is from the Impala board but you shoud check it out.

Cam and Smog Info

If you are considering a smog legal cam then you will probably
find a lot more discussion on the Impala board than this one.
This is not a "baby cam" board. There are only a few of us out
there with the mini bumpsticks.

 

Stick with under 225/230 @ .050 and keep a pretty wide lobe separation (112 to 114) to keep good idle and make the computer happy.

 

great information. thanks guys.

thanks for the impala board link. lots of info in there. what are you refering to as baby cam board??

 

I passed Ca dyno test with a CC305 in a stock LT1 with 100k miles on it. Results below

212/224 @ 0.050" with 114 LSA Comp Blower Grind, AFR 190 heads, SLP Shorties and Vortech blower passed like it was stock.

 

What I mean is that most of the folks here that do cam changes
put in some fairly agressive numbers. The smaller cams you see
are the 306s and the 503s, with a small minority with smaller cams.

I'm talking baby as in the Crane 227 (210/224 @ 112) versus cams
with intake durations in the 220+ range. Many on this board also
consider the hot cam a baby cam.
