No doubt much of his knowledge stems from a life in the competitive arena of race engine building. Raw, un-ground camshafts have a case-hardened rim on each lobe that penetrates this working surface by 0.200in to 0.250in. When finish-ground, the case-hardened surfaces must achieve a minimum depth of 0.100in. If less, the lobe will be …

Regrind roller cam

Many cams have only .080" or less of heat-treat. Cams can generally be ground +/-3* in LSA, and +/- .025" in lobe lift. These are the more important numbers. So this means you cannot regrind a .370" lobe lift, 106 LSA cam into a .450" lobe lift, 112 LSA cam. The grinding process with go through the heat-treat on both the nose, and on the …

Camshaft lobe design

As we all know, the purpose of a camshaft is to open and close a valve at a certain time; the camshaft is defined by valve lift, and duration which is further defined as opening and closing points. But through those three points (open, lift, close) an infinite number of curves can be drawn. Each curve (lobe shape) will determine how the valve ...
