Went to a friends and checked out my block bottom. He is doing the machine work for me. He is building new seal housings out of 6061 and setting one end up for mwsc crank trigger. I needed the cam pin bore in the block repaired so he sized down to k series cam pin bore and we put some high speed needle bearings in the camshaft. So no more bushings in the cam. Using 1/2 inch drill rod for the cam pin. My buddy sent it out to be hardend. Don't know if it will free up hp but it should a little. The end plates will be crazy awesome when done. Can't wait to show it off.
