California DMV engine change rules...?

no smog inspection required on a 1972 vehicle
you put anything you want to under the hood
Whereas this may be true it isn't the way the law is written. If for what ever reason a car is needed to be checked it will need to pass the OEM under hood check for that year. If your car was reported for blowing smoke out or...? Has it ever happened? Can it happen, yes.

You are only exempt from the biennial inspections, not the other aspects of the California smog code.
