Holley carburetor-rebuild articles have been published by the thousands ever since the first four-throat atomizers appeared back in the '50s. Suffice it to say the Holley four-barrel carburetor has been thrusting posteriors successfully for four decades with no end in sight. Mustang & Fords is no exception to the rule about Holley carb print media. We're right in there with the rest. However, anytime we find a fresh idea out there for improving the venerable Holley, we like to share it with our readers.
Meet Jones Performance Fuel Systems of Southern California. Our 715-cfm Shelby Holley carburetor needed a freshening up after napping atop a 289 High Performance engine that hadn't run in ages. The dry and dusty beast needed a complete teardown along with important steps for improving performance that few enthusiasts ever pay mind.
Jones Performance took a look at our Holley and concluded it was a salvageable piece. Jones knocked it down, cleaned it up, machined those critical surfaces, and reassembled the unit for our cameras.
