Stock 302 output was advertised at 146 bhp at 3300 RPM and 270 ft/lb (no RPM specified). Most of these engines were equipped with governors to limit output. I have some factory dyno prints from 196? that show somewhat higher numbers from a 302 with no accessories or muffler, and optimum spark advance: 168 HP at 3600 RPM and 275 ft/lb at 2400 RPM. The torque curve is virtually flat from 1200 RPM until it starts dropping off at about 2600.
