430 mel and ford truck parts interchange ???
does anyone know whether the ford truck 401 477 534 motors were based on a mel block and cyl heads or are they FE style i can recall reading in a 1958 car mag that the 534 truck crank would fit the 430 block ANY info appreciated thanx john

I'm guessing the crank won't fit. Bore spacing on a 430 is 4.9" and it looks like it's 5.25" on the super duty.

I found this post from a while back:
