Something is hitting on the block IMHO. Some mini starters have an electrical adaptor mounted that can interfere. It can be removed. Is this going on a big block or small block?

Big block. Not sure of the year though. The estate I bought the car from didn't really know too much about what was done.

Didn't see it mentioned, but some mini starters are cast with a protrusion near the gear area that makes them not seat fully.
If you locate that and grind it down/off it might work.
The one I had however, would not even seat correctly with that casting as it was.
I could get one mounting point, but not both.

Precisely , it's a combo pack of grinding the starter gear boss and the block casting as shown.
The grinding is the easy part.. the checking carefully that the starter seats flush properly is the part that most don't or can't do.
