heck.... it could be a 352, 360 or 390 if it was that old of an engine swap...
i still have an old ford that has a 390 in it, which at some point will probably get taken out for the 429 i have sitting around....
but that is a whole other project down the line... :redneck:
The only way to tell is check the stroke, maybe I'll get lucky and have a 428 like half the highboys on craigslist:haha:
