[QUOTE="Quick Strike, post: 12101955, member: 11920"] Lobe Separation = (Intake Centerline + Exhaust Centerline) / 2 In your case we have the Intake Centerline (110*) and Lobe Separation (114*) from the cam card, so it goes like this: 114 = (110 + EC) /2. This translates to: 2 x 114 = 110 + EC. That reduces to 228 = 110 + EC. That translates to 228-110 = EC. That reduces to 118 = EC. So the Exhaust Centerline = 118* for your cams as derived from the card. Exhaust centerlines increase in number as they are advanced and intake centerlines decrease in number as they are advanced. We know your cams are advanced 4* since the intake centerline is 4* less then the lobe seperation angle and the exhaust centerline is 4* higher then the lobe seperation angle. You can trust the math and the formula - HTH ;-) [/QUOTE]
