canadian or american?
canadian would still be a poly motor thus a 727.
amerian would be the normal 318 and have a 904 at that time.
not always true I am sure, but generally speaking that is how it would have been.
I'll comment on the American side, it would depend on what application it came from IE: A, B, van or Truck.
Their wasn't a 318 offered in the A bodies in 67. The commando 273's could have had either, but generally had the 904 UNLESS it was really optioned out IE: 67 Formula S, 273 commando, disc brakes, 8-3/4 etc or possibly a tow package. On the tow package
The B bodies could've had either.
Vans and trucks all 727
