Steve, the reality is that the inactive partner will refuse to spring
the extra bucks for a reman engine... So, you and active partner will
have to pay the difference... Based on your posting I suspect that is
not in the works... You will, in the end, decide on replacing the cam
and lifters and taking a chance on the engine making TBO.... No FBO
would OH at 750 hours - he would IRAN and put it back in service...

So, quit gnashing teeth - consider you and active partner pulling the
engine in the hangar, boxing it, and shipping to the engine shop for
IRAN... On return you two move the plane to the A&P shop, help him
with the install and get his sign off on the logs... Easy money for
him, less expense for you, and both of you get some great experience...
win-win...
