TORRANCE, CA - Ideal for high-horsepower and large cubic-inch big-block Chevy dragsters and more, Edelbrock's new 304 stainless steel Down-Swept Drag Race Headers #6551 have big pipes for big power. During on-track testing, racers were impressed with the high quality all stainless steel construction, including the beefy 3/8"-thick stainless steel flanges.

These free flowing drag race headers have innovative features to maximize power potential in competition. The primaries are 2-3/8" at the flange, stepped up to 2-1/2" with 5-inch diameter collectors to match the high air-flow requirements of large cubic-inch big-blocks. They are engineered with the correct firing order pulse sequence in the collector to take advantage of the 4-7 swap firing order that is popular today. Unlike some competitor's headers that interfere with body panels, primary pipe-to-body clearance has been maximized to provide ample clearance, even with wide-body dragster chassis designs. The tough stainless steel laser-cut port flanges are robotically welded and contoured for a perfect fit with no leaks. A true merge collector features an expansion cone on the exit of the collector, and the slip-on design allows for tuning of the primary tube lengths to individual engine requirements. Collector retainer brackets, scavenge tubes, gaskets and all hardware for installation are also included.
