I have been going through the same questions with engines etc. Its really important that you speak with your engineer as the rules change in every state.
As of last monday, the discussion with my engineer regarding engines (I'm putting a ford 4.6 DOHC out of a 04 Mach 1 Mustang into a Harrison)is that all engines from the US post year 2000 are considered to be Euro3 compliant. My engineer (Ray Cross) has this in writing from the federal govt DOTARS people. The problem still lies with the various state people accepting the federal ruling. If accepted by the state people this means that these engines will get a further 3 year extension. the biggest problem is with the Crate motors as there is no way of verifying their build dates. Ford crate engines will not be accepted past the end of this year, but an engine out of a registered or VIN'd car post 2000 will go through. Don't know about GM's I'm a Ford Purist (Go the Ford's).
You can go onto the US Ford web site, US EPA site and the California Clean Air Board web sites and download the actual engine certification documents for all Ford engines. In my case (the 04 4.6DOHC) it is certified as LEV I for California and Tier II for the US EPA (These are both considered to have an equivalency of Euro 3).

As the other guys have indicated, this is a mess between the states and you really must speak seriously with your engineer before making any decisions or committing any money.

Good Luck
