Tore in to it today. Plastigauged the rods and mains. Both show .002" to .0025". End play is at .008". All bearings and journal surfaces look decent. everything at the crank is at the high end of spec. I don't think any thing here is the source of the knock. Pistons are another story. They are running .010" to .022" smaller than the bores. The bores are good no scores, just what looks like normal wear. Crosshatching is still visible in the ring area. I had change the timing chain and gears in the spring of '12. They look OK. Right now I'm thinking piston slap is the source of the knock. It was the loudest when the engine was fully up to temp.

Guys, I've finally come to the conclusion that this stuff is heavy and I am no longer 16. But that aint gonna stop me!
