Classic Chevy owners will love these big block V8 chassis headers for 1955-1957 cars.  They have 34"-36" primary tubes for lots of power, but they're tucked close to the body for maximum ground clearance.  The manufacturer says that they won't work with manual transmissions due to clutch linkage issues!  These headers are finished with our Armor Hot Coating. 
Quality steel construction 
Mid-length design offers maximum ground clearance, even if car is lowered 4"

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. These  headers feature long primary tubes that help produce more horsepower and  torque than shorter, more compact headers. Plus, the AHC ceramic coating provides additional horsepower gains along with decreased heat soak of other engine components.
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.

2" primary tube O.D.

3-1/2" collector tube O.D.

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".
