I was wondering if I would see any performance increase by changing my cam timing. When I built the motor last winter and put the cam in, I just used the center slot on the cam timing gear. There is two other slots, one for 4 degrees advanced and 4 degrees retarded. I was not sure on whether to advance or retard it so I just used the center notch. I have to pull the engine out before the summer for and oil leak and was thinking about changing the timing to see if that does anything for me.
