Do Cam Manufacturers Grind Advance Into Their Camshafts?
112 + 112 = 224 /2 = 112 degrees LSA. In the case of the LS cam, we know the intake centerline is 107 degrees ATDC and the LSA is 112, so if the exhaust was the same number of degrees from TDC, that would put it at 107, but adding 107 + 107 = 214/2 = 107 and the cam cards indicates that the LSA is 112 degrees.
