I have a 79 ford mustang 302 5.0 which runs good but it has the stock 2 barrel on it. I am dying to put a new intake and 4 barrel on it. I live in smog control California and I was told if I did the swap it wouldn't pass smog. Is this true and is there anyway around it.
Check out Summit or jegs, look for parts that are CARB certified
California Air Research Board
I know Edelbrock has carburetor/intake sets that are CARB certified
