We assembled all of this onto the Ford Racing 306 at our tech center before hauling the now complete engine out to Westech for some expert dyno tuning as well as a few high-revving dyno pulls. What Westech found was that the selection of parts was actually pretty well matched to make good power. They did bump up the stock jets in the Holley Street Avenger from 63/73 in the secondary/primary to 65/81 since the engine wanted a little more fuel. After Steve and Eugene figured they were on the sweet spot, they bumped the timing from 34 to 36 degrees and they found the best numbers and smooth curves. Using 91-octane, the max horsepower was 350 at 6,100 rpm, while max torque was 328.6 lb-ft at 4,600 rpm, which were both better numbers than what Ford Racing rated the engine. In fact, the engine was still making horsepower when the valves started to float a little so the rev limiter in the Pertronix distributor was set at 6,000 rpm just to be safe.
All in all, we were very pleased with how the whole build and testing went. This engine will be perfect for the '54 F-100 that will soon be getting a heart transplant!
