After the successful introduction of the FLH Super Sport Solo Panhead in 1955, the factory felt that its high compression motor needed a special cam to deliver the full potential, or Z-O-O-M in Milwaukee speak. So for the following model year the FLH received a performance cam, called "Victory" or "H" cam. The works magazine "The Enthusiast" claimed a significant increase of 12% in horsepower and torque over the FL models that would make the motorcycle "take off like a guided missile". As a unique feature the H cam has different intake lobe profiles for the front and rear cylinder (see chart). This was done by the MoCo to even-out the fuel distribution and the power between the front and rear cylinders. The Cannonball reproduction of the Victory cam is precisely manufactured, with measurements and specs taken from a perfect original example.
