Before I order the engine, I'm going to talk to Pelican about the tensioner upgrade job. It looks pretty tough in the photo guide but if I'm throwing out the engine and it's a core only, it makes taking a shot at it more attractive. I don't know any indy mechanics in my area that can handle a job like this. The other motor looks good, plus the guy noted the IMS was non L&N, seems he's up on his M96.
here's the unit I'm looking at
