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").

Drivers side A dimension is 3-1/2" up by the head and 5-5/8" at the collector
B dimension is 15", and C dimension is 21"
Passenger side A dimension is 4" at the head and 6-5/8" at the collector, B is 15", and C is 21"
