METERING BLOCK UPGRADE - Part Number 34-11
Metering Block Upgrade, 2-Bbl Circle Track Carburetor For 350 CFM 2-Bbl (List 7448 or List 80787) Late Model type metering block upgrade. For high horsepower engines where there are no rule restrictions on the metering block. This highly modified metering block expands the performance potential of the 350 Two Barrel carburetor. GENERAL : Two barrel carburetors used on racing engines offer a unique challenge to teh tuner. Carburetor size restrictions are intended to be an "equalizer" or simply as a means to slow certain classes down. The primary problem is even modestly built engines can easily out-run a small two barrel carburetor. By out-run we mean the engine airflow requirement far exceeds the original design capacity of the carburetor. When that happens, the air/fuel ratio gets progressively richer, robbing horsepower. These modified metering blocks help to correct that problem through recalibration. When compared to a stock unmodified carburetor, these metering blocks add high RPM horsepower by flattening the upper RPM fuel curve.
