*In 1963 Ford released the 289 High Performance engine which produced 271 BHP @ 6000 RPM. Stronger connecting rods with 3/8" bolts, thicker main bearing caps, solid lifter cam, screw-in rocker arm studs, machined valve spring seats, forged steel exhaust valves, a dual point mechanical advance distributor, and better flowing exhaust manifolds rounded out the package. The engines used in the 1965-67 Shelby GT 350 Mustangs, rated at 306 HP, featured a high rise aluminum Cobra intake manifold and Tri-Y headers.

The 289 HP featured a high nodularity cast iron crankshaft that was Brinell hardness tested to ensure quality. To prevent 4th-order harmonic vibrations from destroying the crankshaft at higher RPM, the engine used a different vibration damper and an add-on counterweight. A portion of the 28.2 oz. in. imbalance found in the normal small block damper was moved to the additional counterweight. Moving the mass in towards the front main bearing reduced bending loads on the crankshaft. The special damper also had a larger more massive inertial ring. The add-on counterweight was 0.150" thick. As a result a special crank sprocket was used, C3OZ-6306-A, itself being 0.150" thinner than the normal 289 sprocket. The counterweight waas both keyed to the crankshaft and indexed to the sprocket with a 1/8" roll pin.
