Cam phasing is the relationship of the camshaft position to the crankshaft position in reference to TDC. A change of 2 degrees at the cam gear equals 4 degrees at the crank. | Cam phasing is the relationship of the camshaft position to the crankshaft position in reference to TDC.

| + | {{NOTE1}}When advancing/retarding the cam, be sure to check valve to piston clearance. Each degree of change effects valve clearance approximately 0.010". Example: If you advance the camshaft 4 degrees, you will '''lose''' about 0.040" clearance between the intake valve and piston, and you will ''gain'' about 0.040" clearance between the exhaust valve and piston. It will be the opposite if the camshaft is retarded. | ||
The cam timing, or phasing, can be changed at the time of installation by using a multi-keyway timing set, or an adjustable cam gear like [http://www.cloyes.com/HighPerformance/Products/HexAJustTrueRollerSets/tabid/383/language/en-US/Default.aspx Cloyes Hex-A-Just]. | The cam timing, or phasing, can be changed at the time of installation by using a multi-keyway timing set, or an adjustable cam gear like [http://www.cloyes.com/HighPerformance/Products/HexAJustTrueRollerSets/tabid/383/language/en-US/Default.aspx Cloyes Hex-A-Just]. | ||
