I don't believe that you extend the bore on the magnum 318 to that of the
magnum 360 ... walls are too thin. The magnum 360 uses a different crank
and the web (place where the crank moves) is stronger. I think the mount
on one side is also different.
The magnum 360 longer stroke is the key to its tremendous torque.
