My Engine Is Stamped

I've been trying to ID some specs of an engine that apparently came out of an irrigation pump. The engine is stamped. E77 on the head. Then 1ND23C on the side and 7452C in another place. I scoured about 100 websites tonight and am no closer to an answer. Can anyone help me decode these so I know what engine I actually have.

Cheers

Its a Ford.

It has a chrysler plate that mentions the irrigation pump numbers but not the engine

A picture would help

or at least what end of the engine, the distributor is.

It is an L head and the distributor is in the middle.
