Holley 4160

Holley 4160 is a four-barrel carburetor with vacuum-operated secondary throttles. The 4160 family uses a primary metering block and a secondary metering plate, giving it a simpler metering arrangement than a 4150-style carburetor.

Application / fitment

The 4160 designation identifies a carburetor family rather than one specific calibration. Airflow rating, choke type, fuel-inlet layout, jetting and application must be established from the LIST number stamped on the carburetor body.

• part type: four-barrel carburetor
• mounting flange: square-bore on typical 4160 versions
• secondary throttles: vacuum operated
• selected American V6 and V8 engines using a compatible intake manifold
• production, replacement and performance applications after LIST-number confirmation
• do not select by the 4160 model designation alone without confirming calibration and airflow

Read the LIST number and verify flange condition, fuel pressure and linkage compatibility before installation. After startup, set fuel level, idle speed and mixture according to the instructions for the exact carburetor version and check every fuel connection for leakage.
