California's smog standards are like most of the US. Pre 1976 model year vehicles are exempt, and that applies to the car; not necessarily to the engine. You may install whatever drive train you want in your pre-1976 vehicle and you're smog exempt. I have a friend who has an early 60" Impala SS and has a modern corvette engine in it. He doesn't have to mess with smog..... You can go the DMV website and they'll explain it in legalese.

We Californians have to stick together; even if it does get us sweaty.
