I'm thinking no one had the heart to break it to me. ITS THE MAIN BEARINGS!

I dropped the engine and vowed to keep removing bolts until I found the problem. It was taking about ~30 ft-lb to rotate the crank with spark-plugs out, and still 10 to 20ft-lb with pistons removed. When I split the case, it was quickly apparent the main bearing were in bad shape. I'm surprised this motor was running all and should be thankful it got it self home in one piece.

I am now the proud owner of a precision German jig-saw puzzle, complete with extra starter motor. Looks like a full rebuild is in order. Or, as my youngest daughter suggested, we could tow the van around to the back yard and make a playhouse / spare bedroom out of it.
