So yes, the PRV used in the DeLorean is a SOHC engine. DOHC would refer to a motor that utilizes 2 camshafts per valvetrain. Motors that utilize a singular camshaft located above the crank, and connect to the valves using connecting rods are refered to as Over Head Valve engines. Or, OHV for short. -Robert vin 6585 "X"
