SRA297	-302ULX	-8A3
The first combination of letters & numbers always pertain to the intake lobe. In this example, we have an SRA series roller profile on the intake that has an advertised duration of 297.	The second set of numbers, after the dash, pertain to the exhaust . In this case, we have an advertised duration of 302 and it is from the R-ULX series.	The last set of numbers pertain to the lobe separation. Here the 8 means there is a lobe separation of 108 degrees. The "A" means there is advance built into the cam. The 3 means there is 3 camshaft degrees of advance built into the cam, this will total to 6 crankshaft degrees of advance, giving you an intake centerline of 102 & exhaust centerline of 114.
