Camshaft lobes or cams on a standard V8 engine are arranged in pairs of one intake lobe and one exhaust lobe that are phased to each other. Lobe separation describes how intake valves react in relation to exhaust valves in a cylinder. The wider the degree of the angle between them, the longer the time between opening and closing. Lobe separation determines where peak torque occurs within an engine's power range. Tight lobe separation is under 112 degrees. Tight separation causes torque to build early in the RPM range, giving good acceleration. Wider lobe separation, around 112 - 116 degrees, sees torque building over a wider RPM range, creating more power as RPM increases.
