A few more sneaky hotrodder tricks would include opening up an old timing gear until it's a snug slip fit on the cam instead of a press fit, and using offset Woodruff keys to tinker with advancing/retarding the position of the cam. Advance a cam for more low end torque, and retard it for more top end horsepower. An adjustment of 3-4 degrees can make a big difference in where the usable part of the power curve is located.
