Metering Blocks & Plates

350 CFM 2 bbl Metering Block Upgrade - Used in circle track racing when rules require "stock" (unmodified) metering block. Externally the block looks original (stamped ID numbers may not be be original), however it has been modified to lean out the high RPM fuel curve and make more top end power.
