I say these are New but they have been mocked up and installed in a short lock before. That's as far as it went.
As you can tell from pic they have never been fired up. All info is in last pic but these are for an 18 head. 1/16, 1/16, 3mm ring sizes. This will make a 393 cubic inch race engine.With a longer rod and smaller stroke crank it would make a smaller cubic inch engine. The wrist pins are included as well as the Total Seal rings they were mocked up with.
