Honestly looks like a board track racer motor, possibly a modern mod class project

Yeah I think its 4" bore & 3.750 stroke. Heads look like a small block chevy head with 1 cylinder cut off. I'm trying to acquire it & some more pics & info on it. I was thinking possibly used in a para glider maybe. I know its F'N cool!!!

All billet aluminum for the block, the cylinders I vaguely remember looking like harley davidson cast iron jugs. But it's been soo many years since I've seen it.
