4 Barrel 850CFM Double Pumper Carburetor

This 4 barrel 850CFM double pumper carburetor is a mechanical secondary performance carburetor built to feed serious horsepower on race and high-output street engines, and it carries the BR-67201 reference for easy cross-matching.

Overview

This 850CFM double pumper carburetor is a four-barrel mechanical secondary unit made for racers and engine builders who need consistent fuel delivery at wide-open throttle. The BR-67201 carburetor pairs an 850CFM flow rating with dual accelerator pumps to keep the air-fuel mixture stable during hard launches and rapid throttle changes. It suits drag cars, circle track machines, and aggressive street builds that have the cam, heads, and intake to use the extra airflow.

Built For Performance

• 850CFM four-barrel airflow rating supports high-rpm power on built engines
• Mechanical secondary operation gives direct throttle control under hard acceleration
• Double pumper design with dual accelerator pumps for crisp throttle response
• Four-barrel bolt pattern matches common square-bore performance intake manifolds
• BR-67201 reference for straightforward cross-matching and reordering

On-The-Job Use

• Drag racing launches where throttle response off the line matters
• Circle track and oval racing where the engine stays in high rpm ranges
• Hot rod and muscle car builds running aggressive camshaft profiles
• Engine dyno sessions and carburetor tuning work

Specs At A Glance

Good To Know

Q: What size engine does an 850CFM double pumper suit? A: An 850CFM four-barrel works best on larger displacement or high-rpm engines with supporting cam, heads, and intake. A smaller engine may need a lower CFM rating to keep throttle response clean.

Q: Is this a direct bolt-on carburetor? A: It uses a common four-barrel square-bore bolt pattern, but linkage, fuel lines, and jetting often need adjustment to match your setup. Verify your intake manifold flange before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
