    Division 3 or 4 jd G

    Wow that’s very impressive. Do you think you need all of those cubes to be competitive? Or could a guy do it with a small bore big stroke? I imagine the head helps a lot being able to flow so much air

    770 diesel puller

    Will a crank from a 880 diesel swap into a 770 diesel or are the main bearing journals a different size? That 1/4 inch of stoke could be easy power

    John Deere 70

    I’ve heard people say that there is more room for stroke on a 70? And also that the 70 transmission is much stronger than a G? Maybe it would be better to just build a G like everyone else?
