Camshaft overlap chart
WebOverlap can be calculated by adding the exhaust closing and the intake opening points. For example, a cam with an exhaust closing at 4 degrees ATDC and an intake opening of 8 degrees BTDC has 12 degrees of overlap. But keep in mind that since these timing figures are at 0.050" of valve lift, this therefore is overlap at 0.050". WebWhen the camshaft is single pattern (intake and exhaust cam profiles are the same) and the opening and closing sides of the lobes are the same shape (symmetrical) it is a simple procedure to check the phasing of the …

WebLift. One of the camshaft's most fundamental tasks is to transform its rotating motion into linear motion or lift. This is accomplished on a typical Chevy V-8 with 16 lobes (an intake and an exhaust)--all of them ground to an eccentric shape called a lobe to allow each lifter to raise and fall above a base circle.
