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).
120-400 = .100" jet (Edelbrock p/n 1428).
Secondary Metering
The factory calibration jet is shown in the center column. For leaner or richer calibration
use the jet # indicated in the appropriate column.
