Edelbrock Performer Series Carburetor Calibration Kit 1487 — Metering Rods, Jets & Springs for 1406 Tuning

The Edelbrock 1487 Performer Series Carburetor Calibration Kit is a complete set of metering rods, jets, springs and hardware designed to fine-tune your Edelbrock 1406 carburetor for improved throttle response and drivability.

This calibration kit gathers the small but critical components needed to optimize fuel metering across different operating conditions. Instead of sourcing individual rods, jets and springs, the 1487 provides a matched assortment so you can test and install the right combination for your engine, fuel, and driving style. It’s sold as a kit and intended to help you tune your carburetor without long parts delays.

How will this kit improve my carburetor’s performance?

The kit lets you change metering rods and jets to alter fuel flow at various throttle positions, helping eliminate bogging, hesitation or overly rich running. Fine adjustments can balance fuel delivery for better throttle response and more consistent idle-to-cruise transitions.

• Multiple metering rod sizes to refine fuel curve
• Varied jets to adjust main and idle fuel flow
• Step-up springs to tune progression from idle to part throttle
• Retaining springs and hardware for secure installation

What parts are included and how do they fit my carburetor?

The 1487 kit is packed with an assortment of metering rods, jets, step-up springs and a pair of metering rod retaining springs, plus the small parts required for installation. It is specifically compatible with the Edelbrock Performer carburetor family when paired with part #1406, making it a straightforward swap-in for that model.

• Assorted metering rods and jets for tuning flexibility
• Step-up springs to control rod lift and fuel enrichment
• Metering rod retaining springs for secure fitment
• All necessary small parts included to complete calibration

When should I use this calibration kit instead of replacing the carburetor?

Choose this kit when the carburetor body is sound but the engine needs better fuel metering or you want to adapt the carb to different fuel types, altitude, or cam profiles. Replacing individual jets and rods is a cost-effective first step before upgrading to a different carburetor.

• When dialing out hesitation or rich/lean spots
• To adapt to different fuels or altitude changes
• When changing camshafts or intake setups that alter fuel needs
• For seasonal tuning or performance optimization without a full rebuild

Who is this for? The Edelbrock 1487 Performer Series Carburetor Calibration Kit is aimed at enthusiasts, home mechanics, and professional tuners who run Edelbrock Performer carburetors—especially those using part #1406—who want precise control over fuel delivery. If you maintain classic V8s, hot rods, or street/strip engines and prefer to fine-tune your carburetor rather than replace it, this kit gives the essential parts to dial in performance. It’s sold as a kit for convenience and includes everything needed to pursue better throttle response, smoother transitions, and more predictable running across operating conditions.

Key notes:

• Fits with Part #1406
• Sold as a complete kit for tuning convenience
• Includes an assortment of metering rods, jets, springs and retaining hardware
