Hello,

There are guys who post here who know a lot more about this than I do.

With that said, when I registered mine two years ago the important factor was the "year of the block". If a current block (new crate motor) then they hold you to current emissions standards. That's why I went with a hand built motor with a seasoned pre-'74 block (mine is a '72 block). When they inspected the car, they checked the marking on the block to be sure it was pre-'74 and then they issued me a letter indicating such. No further problems on registation.

One other thing, my registration is a normal registration. I have a collectors inspection sticker in the window (triangular sticker) - which was issued at the local inspection station. I did that because the bi-annual inspection was even more limited than with the pre-'74 engine letter (essentially they limit to checking the odometer and horn). I see no indication on my registration card that it is other than normal.

I hope this helps answer the question (at least as far as the rules that existed back in '05).

Mike
