The Edelbrock Total Power Package(R) concept of selling dyno-matched components has been popular since the 1980s, but with the introduction of the Performer RPM Power Package Top End Kits, Edelbrock matched parts are now available under one part number! Our Top End Kits have been a huge hit due to their all-in-one-box convenience and "no guesswork" performance appeal. With just about everything you need to top off your Chevy, Chrysler or Ford, these Top End Kits are performance-proven.
