I thought the $1300 sounded a little low.  Even with a runout of 0.0045, the Lycoming Factory recommendation that I recall is a complete engine teardown with magniflux inspection of the crank to all critical parts.  This applies to any engine and prop that comes into ANY contact with the ground.

If this sounds a little harsh, especially in view of a wooden prop contacting the ground,  think about the event after OshKosh a couple of years ago when the factory pilot and salesman lost his life when the crank unwound and the prop departed.

More of us than you would imagine have been in the situation you have described--a whooping 30% by some estimates.  The smarter ones bite their lip and take the engine to the shop for a factory recommended inspection, which always mandates tear down and magniflux.

The really unfortunate problem, as I see it, lies in purchasing a used engine.

If you put a used engine on the nose of your project, make sure it has has a factory approved method of rebuilding--the current estimate is that 30 %  of the engines out there have had ground contact!
