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

Note: This header actually goes upward from the head instead of down before dropping over the frame rails. From the top of the head flange to the top of the tubes is approximately 9-1/2".

Dimensions: From the top of the flange to the top of the tubes is 9-½”. Once leaving the ports, the tubes turn upwards and then out to clear frame and suspension. Dimension from block to furthest out point of collector is 25-¼”. Dimension from top of flange to bottom of collector is 5-½”. Dimension from front edge of flange to end of collector at rear is 29-¾”. These dimensions can be compared to your vehicle but should clear most big block application vehicles with normal engine location.
Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.
