The engine was pickled while still on the airplane? Interesting. Why? I mean why was it taken out of service? Prop strike or ? One of the major tells of the condition (says my AME) is crankshaft runout - any idea on that? Why would the mags have only 100 hours if the engine has only 600-ish? Curious minds want to know!
I get the feeling that you are posting on behalf of someone else and likely can't answer these questions.
That's a pretty good price for a relatively low hour engine including the rest of the package.
