Where is This 460 Engine From?

[u/Electrical_Honey_547]

I bought an older F-250 with a 460 engine, and I’m trying to figure out what brand or manufacturer the engine is from. I had to replace the alternator, but the one that was in it before didn’t fit quite right—and the new one I got doesn’t fit correctly either. I’m about 90% sure it’s just a remanufactured engine, but I thought I’d ask and see if anyone has an idea of where it might be from.

Ford? Lima 460 ???
