Info

These Speedway headers allow you to keep the exhaust system under your '55-'57 Chevy car. The "3/4-length" design provides more ground clearance than full-length headers, yet makes more power than "shorty" style headers. These chassis headers fit 283-400 S/B Chevy V8s and has 1-5/8" primary tubes with 2-1/2" collectors.

  • Mid-length design offers maximum ground clearance
  • Designed to work with stock or 605 power steering box
  • Fits cars using an original V-8 pitman arm (some aftermarket arms may cause an interference)
  • Will work with side engine mounts with engine in stock location
  • Fits standard and Vortec-style small-block Chevy heads (not D-port, LT-1 or ZZ-4)
  • Does not work with stock clutch linkage
  • The use of a shorty spark plug may aide in clearance between the plug wire and header primary tubes

Includes a pair of reducers (2.50" to 2.25").

Dimension Chart (GIF)

  • Drivers side A dimension is 3-1/2" up by the head and 5-5/8" at the collector

Notes

These headers are treated with a light coating of anti-corrosion paint to avoid rust during shipment and on the shelf. This coating must be removed entirely before painting with a high-temp paint for final installation. Coating can be removed with lacquer thinner.
