Well I got my .008 side clearance! I disconnected the rods and pulled them down past the crank journal. I got some 400 wet/dry paper and a sanding block and worked on the rods tightened with the shims in. I had a nice flat sanding surface and the babbitt came off evenly. It took me a couple of trys to get my clearance but I finally got all four. I also double checked the rods which are still between .0015 and .0020. Cleaned them up real well and put assembly lube on them. I don't think any engine with assembly lube and close tolerances is going to be easy to turn. Each rod individually was snug, but you do that x4 and they are TIGHT! If I added any shims I would be way over specs. If I loosened them to the point I could turn it, the pistons would be swapping cylinders. Am I right about this theory?
