Houston Cars

SOHC - Single overhead Cam: One camshaft per bank of cylinders, located on the cylinder head. Example: A DOHC I4 would have 1 cams, while a DOHC V8 would have 2 cams. Many people forget that it’s one cam per bank of cylinders - that’s very important. The majority of SOHC engines are of the 2 valve or 3 valve design, though that’s not a requirement.
