I am planning out a future build on my 1978 corvette pace car and I live in California so it needs to pass smog. I have found all of the carb approved parts that I want. My question is that If all of the parts are carb approved and I use my smoger carburetor I should not be producing any more emissions than I am now because I will be using the same air fuel ratio I am now. And then I can Just have a different carburetor on it when it is not being smoged. Parts im looking at are:

AFR-1034 - AFR 195cc SBC Eliminator Street Heads
CCA-12-210-2 - COMP Cams High Energy Camshafts
CCA-1412-16 - COMP Cams Magnum Steel Roller Tip Rocker Arms
CLO-8-5100Q - Cloyes Timing Gear Sets
EDL-3701 - Edelbrock Performer Intake Manifolds
FEM-MHP127-000 - Federal Mogul Premium Engine Rebuild Kits
HED-68301 - Hedman Street Headers

The Parts in this list that are not carb approve are the intake, and the rebuild kit which includes Pistons, but i dont think those will affect much any way because I have heard of people grinding of the numbers on the intake and painting it and it looks just like the stock one. Any help with my predicament is very appreciated because I dont want to build an awesome engine and then it wont pass smog.

I believe that specific intake is considered a 'stock replacement part' therefore it doesn't need a C.A.R.B. number/sticker.

I am a novice when it comes to carburetors. So I guess I'm asking more than offering a useable thought! The carburetor on the 78 has additional vacuum lines to operate the diverter valve on the air pump. I'm sure you will need to keep the air pump and you are using Headman headers with the air injection fittings. I don't see why this would affect your build in any negative way? Nor would I think the vacuum lines for the vapor canister would change anything.

So, why would you be concerned about the stock Rochester?

I was just thinking that the Rochester carb would not supply enough fuel for the increase in performance parts given that it is not adjustable.

I don't think you have enough cam or intake volume to support the AFR 195 heads. I would use the AFR 180's.

Why not stroke it?
