After World War II the engine was also licensed to Bristol Cars in the UK.
The M328 had an unusual valvetrain design. While the camshaft was located in the block (as per OHV engines), the exhaust valves were controlled by a transverse pushrod from the intake valves. This meant the valve layout is similar to a DOHC engine.
With a bore of 66 mm (2.6 in) and a stroke of 96 mm (3.8 in), the displacement was 1,971 cc (120 cu in), the same as its M78 predecessor. Three Solex "30 JF downdraft" carburetors were used on the M328.
