If you ever had one just fall out, dumping all coolant, and not know it happened (like at night!), therefore kept on going, until the engine was toast, you wouldn't trust one any further than *absolutely* required.

You say that the 390 was rebuilt; I think, and I maybe wrong, but that block looks like a 360. In the past dealing with the Ford FE engines; the blocks that I have had with the "ribs" on the side of the block were 360 and none of the other FE's that I have had had them.

360 and 390 used the same block & heads, the difference was the crank/rods/pistons.
Either way, the 360 didn't exist in 64, which is when the C4 casting number was first used.

Perhaps in part, but the crank snout doesn't appear to be from a 361/391, and I don't see the tapped hole for the oil drain from the air compressor.

Take a wire wheel to the piston tops, if they're oversize,. the over bore will be stamped into the piston top. As for the block/crank combo, at this point in time anything's possible 40 years after production ceased. The cam thrust plate is also on backwards.
