    Can you get big bore pistons for a 1340 that doesn't require new liners or any machining or is 1340 the biggest you can go on the stock barrels?

    those barrels tend to become unstable when you go big but you can bore the stock cyls, get your local shop to get a set of pistons n get the barrels torque plate bored to fit
