This bolt-on big bore cylinder and piston kit will increase the displacement of 88″ engines to 97″. It is as easy as a stock top end rebuild and requires no machining or flywheel rebalancing. For best performance, appropriate camshafts, performance air cleaner, performance exhaust and fuel system tuning are required.
