It is a Mercury crank with 4" stroke that came with the 1CM block. The machine shop just polished it as it was in good condition. Had to bore the engine 3 5/16 to get a good clean bore. Reusing the original rods had the machine shop check for being round all were good. I had the machine shop install the new Egge pistons to the rods. When I picked the block and crank up I had the machine shop recheck the size bearings I needed. According to him I needed .20 under for the rods which I ordered. I cannot remember now where I ordered the rod bearings from.
