Io540 compatibility for a McCauley

Building an rv10 and keeping an eye out for used parts. I came across a propeller off a cessna 310 that had a 520 engine in it. Wondering if anyone is an expert or knows of an expert in the PNW I could chat with to see if this prop would work. I think the prop has little value since it has no logs but if I could get it for nearly nothing and OH it maybe I'll come out alright.

McCauley model stamped on it: D2AF34C and its 80 inch tip to tip.

Well, for starters, since it’s coming off a twin, it will need the ‘backwards’ governor found on a twin - no oil pressure = feathered.
