This interactive tool shows all possible primary jet and metering rod combinations for Edelbrock/Carter four-barrel (AFB) carburetors. Dig through your toolbox and select each of the jets and rods that you own in "Jet & Rod Inventory". Check the gear ⚙ icon to select your installed jet & rod combination.
Each jet you own is given its own color, and each metering rod is shown as a colored point for that jet, positioned by its effective fuel orifice sizes. A larger "power" orifice is further right on the X-axis, and a larger "cruise" orifice is higher on the Y-axis. Stock carb configurations are shown (by default) in white. On the resulting map you can easily see which combinations are possible with your current — or any other — jets. See "Chart Configuration" for options.
Your selections and configuration are stored for future use on your device using cookies. No information about you or your device is ever stored, shared, or tracked.
