Hot Rods need help with eng numbers

Bought a ford block that I think is a 59a .That has been ground off of the bell. Was rebuilt by Rogers in Atl. The existing numbers on the bell are F28744 ,the 8 could be a 6.Any help where I can find what this equates to?
Thanks,

pictures help too.......

 

Those are foundry numbers that are effectively meaningless. Is there actual evidence of a 59 ground off or is that a guess? A picture of the deck would give actual ID of what flavor of 239 it is. Also a couple pics of top center front of block, above the timing cover.

 

Bruce, it fails the pencil test, and has 2 round holes below the triangular water hole in the block. On the bell I can see a partial of the 5,but nothing else. No ab there.

 

Please refresh me on the 'Pencil Test'. Reminds me of my induction...

 

If there's a 5 and evidence for destruction near it, sounds like a 59. The A generally did not go there, the B has nothing to do with the block at all.
Pencil...slope from top of block to opening for timing gears is a bit like J on prewar blocks, will hold a pencil at bottom, and more like / on a 59. Glad I have this CAD program so I can illustrate!

 

So it's probably a post war block.

 

My take on those numbers, not verified or certain, is that the 59's with lots of those are engines built after production of cars with 59's ceased...engines were built for quite a while to feed the endless postwar market, and I think many of those were built with the cheaper cranks, rods, and valves from the late flatheads. It was easy to keep making them since all the machining and such could be done on the later production fixtures.

 

Thanks .
