I would build that motor and run it but I wouldn't buy it second hand. On the flip though, if you could get it cheap enough and tear it down, check it out, then it's certainly a good set of parts.
There is really nothing crazy about a hybrid in itself. I would want to know more specifics about the cam, valves, what rings and pistons were used, was it an old 22r bottom end with a cleaned up 20r head on it or was it a complete fresh re-build. If you had some idea of what you were getting into, that would be good.
