Mike,

I'm not sure of the numbers, but my state requires existing emissions equipment remain, so I have to keep the EGR on it. I haven't seen that Edelbrock makes a Vortec Performer intake with EGR.

So the cam that came in the 350HO passed emissions with that low CO and hydrocarbons? I was led to believe it was too large a cam to get that low on emissions.
