This bolt-on big bore cylinder and piston kit will increase the displacement from 96" or 103" to 106. 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.
