Not to second guess you, but lots of states will go by the year of the engine as the benchmark for smog requirements etc. In all the process of buying a Kirkham, did you never look into MA's requirements before you bought a crate engine?

(My ERA was first registered in MA, so I have the original owner's paperwork that establishes the block as being a salvaged 1966. It's not a new rule... and ONLY the block is original, not the complete engine, trans, diff or "complete drive train.")

I agree that stuffing a "legal" engine in it to get it registered is the simplest and most straightforward option.
