Big Block Power Combo - Real Fine 509, Part 2 Photo Gallery
For dyno testing, Dart's builders bolted on this Demon 850cfm four barrel. It features 1.560-inch venturis and 1.750-inch throttle blades. Jetting specs include #85 on the primary with a power valve and #93 on the secondary jet and no power valve. The comparatively easy adjustability of the Demon design is appreciated on the dyno.
