John Deere 757 zero repower

I was given a ZTrak 757 mower recently with a blown motor. The previous owner had the kawasaki FH721D motor rebuilt twice (the typical overheating, bent pushrod issue). I retrofitted a harbor freight 22hp predator motor and have about 3 hours on it now. I have no idea how long this retrofit will last but thought I'd throw it out there in case someone else is considering a repower. It can be done. I have some pics and documentation if anyone is interested.
