It has been a while since I posted some Holley Carb Info

Here is a Handy Holley Jet Flow Chart for Jet Calculations

Enjoy

First Column is the Jet Number
Next two columns are the Holley Jet Part Number (example 122 40)
Next column is the Holley Drilled Size (example 0.0400)
Next column is the Jet Area (example 0.001257)
Last Column is the Flow of the Jet in Cubic Centimeters per Minute (Example 117)

The List goes from a Holley #40 Jet to a Holley # 110 jet.
