Can someone ID this motor for me?
Its in a '77 F150 fwd. The guy who sold it to me told me it was a 400. If no one can tell right off the bat, then what? Take the head off and measure the bore and stroke? I thought I saw something that looked like #'s under the starter (passenger side of the block). Maybe I should check the VIN before I waste your time. It may be the original motor.
