Maxom,
You didn't mention what state you are located in. I too looked at the Genesis 427 motor. It is marketed as a reproduction block with a vintage date stamp. However, the registration in my state is very strict, and I could find no precedence for someone getiing one of these blocks through inspection. I didn't want to spend the big bucks for an engine I could not get through inspection, so I opted for an original block with authentic stamps and codes.

I would definitely check with your state DMV to see what you have to do to get both engines through inspection. It may make your choice easier if you find a problem with getting one or the other through inspection.

Better to do your reseach now, then to be caught trying to make your engine legal after you purchase it.
