SOHC stands for Single OverHead Camshaft, in which one camshaft, positioned in the top portion of the cylinder head, operates all the intake and exhaust valves on that head. Thus, DOHC stands for Double OverHead Camshaft, basically the same arrangement but with two camshafts, one operating the intake valves and the other the exhausts. Hope this helps. BTW, why do you ask? Just for information, or are you working on something? Don't be shy; let us know! - Chris
