The engine made 559/540 without a tapered spacer under the carb. We re-dynoed it with a tapered spacer and it ended up making 570.5 ft. lbs. @ 4400, and 539 HP at 5700 RPM. From 4700-6300 RPM it made over 500 HP. From 4000-5500 RPM it made over 500 Ft. Lbs of torque. And it made over 560 Ft. Lbs from 3800-4900 RPM. Over all, the average HP is up 10 from the previous best dyno run from the past. This was with a Carb Jeff custom built for this engine that had previously never been run or tested on anything. I'll try to scan the dyno sheets later and post them.
