Speedway Motors 930C4C Details

These fender well headers provide the ultimate performance for 396-502 big block Chevy V8s in 1955-57 Chevy car applications. They kick up over the frame rail and exit just at the bottom of the cowl, which makes them perfect for Gasser-style rods and drag cars. Plus, these headers feature long primary tubes that help produce more horsepower and torque than shorter, more compact headers.

These headers are not for the faint of heart since you must cut the inner fender panels to make them fit, and tire clearance can be a problem on some applications. They may require smaller front tires to avoid contact. The stock emergency brake rod must also be altered. Can be used with most oil filter systems or transmission and starter combinations. The headers are designed to be used with engines in the stock location, not lowered as many kits do, so all 55-57 cars should check motor mount positioning before ordering.

  • Header flange has 1-13/16” x 1-13/16" port size
  • Will require fender well cutting or alteration
  • 2" primary tube O.D.
  • 32" primary tube length
  • 3-1/2" collector tube O.D.
  • Chrome plated finish
  • Includes bolts and gaskets

Parts arrived as described eventually but I would like to see better packaging. Freight companies can be hard on shipments, especially heavy packages with sharp edge products and loose parts in the box.

Would Recommend
