While supplies last
These blocks are completely unassembled and require builders to facilitate their respective calibration in the blocks.
Blocks are sold bare no internal components.
In the 1980s BLP Products was the first to introduce a fully machined billet metering block for performance Racing carburetors.
Since that time BLP has expanded the billet metering block line to suit the amateur to professional carburetor builder. Green anodized Metering blocks have completely adjustable emulsion, idle feed, and power valve restrictions for the most discerning carburetor builder.
The 5125 series blocks allow for the builder to use the idle feed restriction in the high or low position. Once again allowing the carburetor builder choices in their respective builds.
