Offenhauser part number 5921 is the tunnel ram base for small block Chevrolet engines. This tunnel ram base is designed for use with interchangeable tops, such as the dual quad top (part number 5923) or single carburetor tops (such as 5922). It is widely used in performance, hot rod, and racing applications for small block Chevy V8 engines, including popular engine sizes like 283, 327, 350, etc.

- Compatible Tops:Â Works with the 5923 dual quad top (for two 4-barrel carburetors in line), the 5922 single carb top, and others.
- Carburetor Compatibility:Â When paired with the 5923 top, it can accept Edelbrock, Carter, or Holley square bore carburetors, using the universal bolt pattern.
