Edelbrock Performer Series Carburetor

Step 1: Select the combination of Cruise Mode and Power Mode fuel-metering stages desired for your calibration. Normal calibration changes will be within the gridded diagonal area. That is, Cruise and Power mode changes should be in the same direction (either richer or leaner) and usually by the same amount.

Step 2: Find the number that is nearest your desired combination. This is your Calibration Reference Number.

Step 3: Go to the next page. Find the Calibration Reference Number you have just selected in Step 2. Listed will be the Main Jet and Metering Rod required to achieve the desired fuel metering for the Primaries.

Main Jet I.D.-All Edelbrock jets have "120-"prefix. The last three digits minus 300 = actual jet size.

Examples:
120-398 = .098" jet (Edelbrock p/n 1427).
120-413 = .113" jet (Edelbrock p/n 1433).
