Three factory race cars were fitted with a flat eight-cylinder power plant derived from the 1962 804 F1 car, the 225 hp (168 kW) 1,962 cc (119.7 cu in) Type 771, which used 42 mm (1.7 in)-throat downdraft Weber carburetors.  The Type 771s, however, suffered a "disturbing habit" of making their flywheels explode. The 904/8 cars had a short and relatively unlucky racing career.
