I remember when the whole smog crap and checks started out here. I was still a teen back then and driving my '63 at the time. It was supposed to be smogged the first year except that I had the wrong VIN. My truck was on the off year, at which point it wasn't require because of the age. So I never had to actually smog my old truck.
I had to smog my '62 when I bought it (transfer of ownership) but not since then. I like the concept of PCV, it's good for the engine, but wanted the old look.
I have a unused vacuum port on the rear of the carb baseplate. I will probably plumb what I have into that. I will use my new fitting since I already built it. I think it will look fairly clean. PCV valve will be easy to change if needed. Plug and play just like in the valve cover, just a little farther back on the engine.
C.A.R.B. is still an unpopular government agency out here. I have some horror stories I could share.
