Edelbrock enables hot rodders to shop for everything in one location. Jon Barrett has topped our 514 with Edelbrock 429/460 Cobra Jet aluminum heads. This enables us to run higher compression and net more power. Comp Cams Pro Magnum rocker arms are bulletproof pieces; race ready for Saturday night and reliable for day-in and day-out street use. On top is a Victor Jr. single-plane manifold, good for high-rpm breathing. Although the Edelbrock Thunder Series 800-cfm carburetor is perfect for this application, we opted for an 870-cfm Holley Street Avenger with vacuum secondaries. In front is an Edelbrock Victor Series water pump, which offers high flow and greatly improved cooling.
