    Those engines tend to be a real workhouse with a LOT of Torque and a huge stroke, but a tiny bore which limits them to low RPM and slow revving.
    They are not really a good "Hot Rod" Engine but perfect for what many, many of them were sold for; powering flatbed and stakebed 1, 1 1/2 and 2 Ton Farm Trucks and Dump Trucks.

    Very little speed equipment was ever made for them, but there were as you know, a few Aluminum higher compression Heads and 2 -1 Barrel Manifolds.

    I would bet there is quite a bit of cylinder wall thickness in there if someone had one Ultrasound checked.

      The valves and ports are so small and the stroke is so long, conventional hot rod methods such as a larger bore don't do much. The only way to get a real horsepower boost is to add a turbocharger.

        Hey John, how about adding a Kaiser Supercharger set-up.(McCulloch)
