I'd say you have an early casting 302 block. Should have the standard 8.206 deck height and 4.000 bore. Should have came with a passenger side inlet water pump, dipstick provision in the passengers side of the block, and a 3 bolt 28oz balancer. My guess is that at sometime or another this motor was swapped into the Bronco just because of the date code. Though the Bronco line seemed to a lot of Ford's left over parts. The only special blocks from the '60's would have been the 289HP(C5AE-E) or the 4 bolt main BOSS(C9ZE, D0ZE), but even then the HP block was standard issue with beefier main caps.
'72 TBA...
