I registered my car at about the same time. I went to the local branch office of the state emissions department, and got a letter stating what my smog standards were. I was using a 74 block, aftermarket heads, an 8 stack EFI system, and an electronic distributer. I showed him a picture of an original car with Webers, and he agreed that my engine represented that. So I got smogged as a '65 - I had to meet visual and tailpipe standards for that year.

The car is registered as a 2002 kit. The year of the car is based on the date on the MSO from FFR. Fortunatly, no vehicles registered as kit cars need a smog inspection anywhere in CO.

Nobody ever looked at the casting number on the block.
