    Multiple 260s, 270s, and 280s

    So my buddy runs the parts department for a boat company that restores mostly old woodys and classic fiberglass. He said that they are going to be selling off a bunch of 260s, 270s and 280s that were attached to classic Donzi's. As well as a ton of components.

    454 Piston problem

    I inserted a ring and leveled it with the piston head and took 3 readings. Top, mid, lower. All were identical. I could get a .020 feeler gauge in but met with decent resistance.
