In the 1980's BLP was the first to introduce a fully machined billet metering block for Holley® carburetors. Since that time BLP has expanded the unassembled or assembled billet aluminum metering blocks for both gas and alcohol application. Metering blocks can be custom built with your specifications or purchased bare for the professional carburetor builder.
Features are:
• Available in the following anodized finishes: purple, gray, black
• All fuel circuits are adjustable including power valve channel
• Power valve channels are lowered
• Custom logo engraving available
