    The M1 cranks where hand picked and Brinnell tested for strength and iron content. They used a narrow timing chain to avoid conflict with the hatchet wait used to help balance the use of the large diameter harmonic balancer. Hipo and Boss rods used 3/8 bolts and 9/16 nuts rather than the standard 5/16 & 1/2.

    Hope this helps,

    Also The Front Oil Gallery Holes Behind The Timing Cover Were Threaded With Threaded Plug Caps Rather Then Pressed In Plug Caps
