| It's definitely either a 360, 390, or a 428. |

From 1966-on, part numbers cast into FE blocks mean't nothing. Date codes, foundry symbols, time stamps, and rear-face weld beads (chicken scratches) tended to be correct, however.
Ford seemed to share the various core patters for teir blocks to the extent that only the cylinder cores and maincap web cores seemed to differ. The only thing you could be sure of from the cast-in part number is it was cast on-or-after that year.
The best way to ID a C8 block is to look at it's rear face. Covered up by the flywheel is a "chicken scratch" may be a chicken scratch character about two inches tall, sometimes sideways, apparently scratched into the sand or, more correctly, welded into the casting pattern. If the character is an "A" you have a 1968 428plain or early 428CJ block without the reinforced mains and cylinders. If it's a "C" you have a reinforced 1968-70 428PI, CJ, or SCJ block. If there are no chicken scratch characters, its a 360/390 block.
I repeat: any C6, C7, or C8 block identifiers could mean anything. C5 and earlier is a different story. Life was so much easier in those pre-emission controls days.
