Block, Billet Metering Standard calibration, screw-in idle feed restrictions, secondary block without power valve provision. Metering blocks are a simplet bolt-on component that can upgrade the performance of your existing carburetor. "Universal performance" carburetor calibrations are developed to work on virtually every engine, including stock engines without any performance upgrades. A primary component in the "Universal performance" calibration is the metering block. Upgrading the metering block to a more aggressive calibration is the key to unlocking the true potential of a performance engine. Billet metering blocks offer the highest quality metering performance available in a metering block. Precision CNC machined from aluminum billet, porosity causing cross well bleeding is virtually eliminated. All billet metering blocks have screw-in idle feed restrictions. Standard calibration metering blocks have race breed emulsion calibration pre-drilled directly into the metering block. Adjustable metering blocks have screw-in emulsion bleeds that can be altered for ultimate fuel curve tailoring.
