Edelbrock Performer Series Carburetor Owner’s Manual 3/00
INTRODUCTION
Your Edelbrock Performer Series carburetor was calibrated using Edelbrock Performer, Performer
RPM, and Torker II Power Packages. The carburetor metering was developed on Edelbrock engine
dynamometers, chassis rolls, and a variety of development vehicles. Although in most applications
you will not need to recalibrate your carburetor, you may wish to change the factory calibration to best
meet any unique needs of your engine. The following manual consists of 2 sections; Theory of
Operation and Tuning Procedure. Upon review of Section 1, Theory of Operation, you will be prepared
to develop your own individualized calibration. Section 2, Tuning Procedures will take you through a
step-by-step procedure that will enable you to achieve a desirable calibration. For added ease of
tuning, a Calibration Reference Chart for your model of carburetor has been included.
