Very Interesting. I'm not an expert but I believe the G440 HP or F440 HP (or whatever year) is stamped at the same time the assembly date is stamped on the ID pad along with other engine identifiers like undersized crank or oversized lifter bores. If the stamp was dated June of 1970, and it was stamped "G" 440 months before you could even order a 1971 Plymouth, could it have been a preproduction or pilot car?
