The 817 is similar to the 843 except it has a smaller (64mm) bore. It was used to get below the 50 cubic inch maximum required to be legal without emission controls.I have a set of domed pistons stamped 67. Used. What would these be good for? Came out of a bored 817
Yes, but it's easy enough to do a rough check on piston size and stroke.Thanks Gene, Should I expect these to be 67MM bore?
Hope these photos give you more info. I have to pull the block off the shelf to measure the bores but maybe this will help. Was a stroker crank I believe.
