Sledding - General Discussion
My $30 a pair Seadoo 650/657 (78mm x 68mm) Cylinders, on a 670 Block given to me. Rod is broke, don't know the history of the blown 670.
With a 617 Crank, would make a 650cc engine.
Has anyone, adapted a set of 670 Cylinders onto a 583, 617, Case? If so, what Piston did you use. Yes, the case...
