Hello, I am selling a 8CM mercury motor I believe it is out of a 1951. The block has been dis-assembled. Block has not been mag'ed but has been pressure washed and there are no visible cracks. Most everything is there, block, rods, 4" crank, 8cm heads have been cleaned mag'ed and decked, cam, (no valves or lifters), Comes with a bunch of other misc. flathead parts as well extra heads extra oil pan etc... Great start to a nice build. Asking $500.00. Will not ship, must be picked up and I have a cherry picker and can help load up. Located in Long Beach California. I was going to build it up myself but, realizing I just have too much going on. Here are the specifics: Last rebuild block was 0.060 overbore 4" crank .020 on mains / .010 on rods Thanks Chris
