mech advance distrbutor with dual points, thicker balancer than you'd normally see, hi-po exh.manifolds, if you can pop a valve cover look for cast in spring seats, screw in studs, and the slotted pushrod holes in the head. Obviously, it should have a 4 barrel carb and intake... Other differences would be harder to spot with an external inspection...like solid lifters, larger main caps, and the brinnel tested crank.
I would say to be sketical of it being a hi-po, but being that its free, it will be hard to lose out on the deal even if its a 2v 289.

I guess because there aren't any usable cores left.
My buddy swapped a std/std 289 crank and rods for a 10/10 302 crank and rods and a scad of machine work about 10 years ago because the machinist needed the core.
They only made the 289 for a couple of years. They made the 302 forever by comparision. Why anybody would build a 289 (or worse, a 260) now is beyond me.
Put it in the basement to keep company with that 302 boss block you recently found there. . . . . .
The only reason I can think for rebuilding a 260 or a 289 is to keep a car original.
