The engine rebuild process is just about complete on the 289 in my '62 GT Hawk. It was rebuilt keeping it stock with .030" over on the cylinders, WCFB and Petronix in a Delco distributor. It is my understanding when on the dyno the generator or power steering pump will not be installed. The factory exhaust manifold will be installed. What type of torque and horsepower numbers could I expect - let the guessing begin!
By the way, the whole rebuild adventure can be viewed on YouTube - Pete's Garage (Engine rebuilding).
