Does it have to be an original old (rebuilt) engine, or can it be a new version of the old engine (and how do you prove it)? When I registered mine in Colorado with a Roush 427IR which is a bored/stroked 351W (Dart block, I believe) I was told that the modern "remakes" were considered to be the older engines and thus mine was measured against the 60's emissions (for example, I didn't have to have a PCV system, which was good, because the 8-stack Fuel Injection system didn't accommodate it) and exempt from further emissions testing...
