My merc 470 block needs a skim
My merc 470 block needs a skim. I am going to have the pistons skimmed at the same time as there is no tollorance to play with between the block and top of pistons.
Has anyone got any idea how much tollerance I have to play with between the valves and top of the pistons. Im having about 22 thou taken off.??
