The Edelbrock Performer RPM is a bolt-on performance upgrade for 2003-Present Gen III HEMI(R) 5.7L, 6.1L, 6.2L and 6.4L engines. It's designed to fit with the stock intake manifold, exhaust manifold, valve cover, rockers, spark plugs and accessories, as well as Hellcat components. These cylinder heads have been machined to be used on either the driver or passenger side of the block. They are cast from A356 alum and heat treated to T6 specs, machined and assembled at Edelbrock's facility in Torrance, California for guaranteed quality. These cylinder heads feature fully CNC machined combustion chambers along with CNC profiled bowls and port entries/exits for improved air flow. They also feature more material in the deck and reinforced combustion chambers for increased cylinder pressures. The rocker bosses have been reinforced for improved stability and strength. Extra material has been added around the intake and exhaust ports to allow for porting in racing applications. Both the intake and exhaust port flanges have remained in the factory location for use with OEM components. The intake and exhaust valves have been tipped away from bore wall to unshroud the larger valves, while maintaining factory geometry. The seat diameters have also been increased for improved heat transfer and durability over stock. Match with an Edelbrock Victor EFI #7179 intake manifold for the ultimate in Edelbrock Gen III HEMI performance. ** INSTALLATION NOTE: Incl. all factory accessory holes (Including Hellcat). Compatible with stock valve covers and coils

When you design and sell the best-engineered performance products in the world, you have to have a rigorous testing program. Why? Without adequate testing, there's no way to stand behind your product with confidence. That's why every product we design and sell at Edelbrock is tested and approved by Edelbrock engineers in a real world environment on state-of-the-art equipment. Our three Super Flow computerized engine dynos are capable of measuring 11 separate engine variables up to speeds of 12,000 rpm. For 2007, we added a new Super Flow SF902 engine dyno. It's fully automated and programmable to simulate various driving situations, and is equipped with WinDyn software for the very latest in testing equipment. For real-world tuning, there's our Super Flow model SF-840 eddy-current chassis dyno that can handle up to 1,000 hp at the wheels and speeds of 200 mph. When all testing is completed, the results evaluated, and the part has passed all performance criteria, then, and only then, is the product deemed ready for production. These precise testing procedures are applied to the entire Edelbrock line for performance that's guaranteed. Edelbrock test vehicles are driven by Edelbrock engineers and employees to get a "real world" feeling for the performance improvements. Our products are also tested and used by professional race car teams and drivers. Working with these talented individuals is just another extension of our research and development process so when we say "proven performance" we really mean it! Top racing teams in all forms of motorsports rely on Edelbrock to produce parts that they can count on to win races and championships. Further underscoring our commitment to the racing community, Edelbrock is the only aftermarket intake manifold manufacturer licensed by NASCAR.
