California DMV engine change rules...?

I understand a California motor change is installing a motor outside the original engine family (ie V8 swap in a mini truck) and the smog implications are on the new motor, ie the new motor ( ie.'86 302) must have that years smog equipment functional (egr, evap, pcv, etc) in the chassis it's being installed in (ie. 72 Ford Courier) and then the "smog year" of the truck is now 86 and is checked as an 86. With me so far? So.....what if I installed a '64 273 into an 82 Courier? I have them both laying around and was thinking that would make a snappy little truck. The 273 never had smog and the 82 smog stuff could not work on the 273 unless I used an egr intake with 66+ heads.....just thinking out loud here. 2.0 is 80hp and 120 ft/lbs on a hood day. 273 should be double the torque and HP.
