I have a '79 p/u and it has a 500hp full roller 383 in it. The time for smog (test only) is rolling around and I need some advice from truck people! This engine will not pass, it doesn't have the parts or the heads for it. I could do a possible motor swap every two years...but that will be a PITA. Does anyone know where to find what counties in CA are exempt? I am getting desperate...almost considering doing a non-op Any help, advice, or friends would be greatly appreciated!
