By setting the cam timing "straight up", you will get the performance that your camshaft was designed for by its manufacturer.
In essence, advancing the cam timing will lower the rpm range of the cam's effective power band, retarding the cam timing will raise the rpm range of the cam's effective power band.
Depending on the cam design, you might get more low-rpm torque (and less high-rpm horsepower) by advancing the cam from the manufacturer's specified timing, and you might get less low-rpm torque (and more high-rpm horsepower) by retarding the cam from the manufacturer's spec. This works only if the cam design allows for it, and only if you change the cam timing in very small increments, usually no more than 4 degrees either way from the spec timing.
