1955-1957 Chevrolet Corvette Long Tube Header Hooker Super Competition 2292-1HKR

Overview

These swap headers allow enthusiasts to drop an LS (all exc. LS7) engine into the ever popular 1955-1957 Chevy. These new headers were designed to fit with a stock gear box or Saginaw 605 gear box only. If using a unisteer rack system, see part # 2293-1HKR. They are a true 1-3/4" long tube design to sufficiently maximize the torque and horsepower of the free breathing LS engines. They are available in high temp black paint, silver ceramic or Hooker's brand new "Darkside" black ceramic.

• The left side header incorporate the use of a clearance “flat” modification in one of the primary tubes to provide adequate clearance between the tube and the popular GM605 steering box; the location of this modification is completely intentional and necessary.
• These headers are compatible with most common GM automatic transmissions and can also be used with manual transmissions when using a hydraulic master/ slave cylinder configuration to operate the clutch; these headers will NOT work with the stock manual transmission Z-Bar assembly and linkage. Depending on the transmission you choose to use, the transmission tunnel sheet metal may require modification/alteration to provide adequate transmission-to-body clearance. The required rear transmission mount/crossmember will be determined by the transmission you choose and no specific mount is specified by Holley Performance Products.
• Breaking in an engine with ceramic coated headers WILL result in damage to the coating and will VOID all warranties. Hooker recommends using cast iron exhaust manifolds or old headers during your engine break-in period to avoid damaging your coated damage. Please Contact Us for additional information regarding ceramic coated exhaust products.
• The use of header wraps can cause the header tubes to crack or rust due to excessive heat and moisture build-up. Hooker does not recommend the use of header wraps as this will void the warranty.
