anti-pollution when did it start

the law says the emissions package must be of whichever is the latest model year, vehicle or engine..

This amounts to some incredibly heavy "suckage."

So does this mean that if you were unfortunate (example) enough to have your completely smog free 67 built to the hilt Dodge window a block, and got a late model 440 BLOCK out of, say, a motorhome, that simply using a late REPLACEMENT block gets you into the "lotto smog" arena?

But I think Idaho "sucks" as well

Last I knew, there were only two southern counties that required emissions checks, but up here in NORTHern Idaho (It's a state of the mind) they were rattling around about smog checks, due to Spokane air drifting over here

As far as I can tell, Idaho (unlike, say, CA) gives no exemptions for anything that required smog. That IS one reason I bough a 67, although I'm not effected ....yet
