Imp. EFI system on a 360?



In California, you must comply with state issued regulations as to smog
equipment and certification if the car is newer than 1973.   In other
states, you may have more options, but we have to toe the line out here.
Engine swaps are pretty darn hard to get approved, unless you transplant the
whole engine management system along with the engine, and that includes
EVERYTHING!

Originally, the EFI cars were intended to have the 360, but Chrysler could
not get it to pass the EPA smog rules, thus the 381 was substituted.   If
you were really sneaky, you could install a 360 and make it look like the
original engine, with all the original smog gear and EFI system, and you
might get away with it if it would pass the current requirements for
emissions, but I'd hate to spend all that money and be turned down!
