To assure the usability and integrity of your system, it will be necessary to change several components. The early M cam drive (timing) gears are perfect for driving a cam, but not suitable for the loads placed on them with a live pump. Also, the bolt patern is 1/2 a bolt hole off. The best option is to replace the front timing cover with the one from a late late 51 M or newer, including SM and SMTA, or 400 450. There may be differences in front engine mounts with number series. this will be the correct bolt pattern. I think the 450 cam drive is the strongest set of gears. The threads in the number series may be left handed on the cam gear retaining bolt. Use locktight on the hub and bolt. SOme have gotten by using the original gears. (usually with 850psi pump relief) the 400 system can make 1250 or more, and will break the gears. The relief system is in the resrevoir, so a relief system will be needed if other valves are used.
