Speedway Motors 930C7 Details

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"

Overall Assessment

Customers praise the product for its excellent fit in a variety of builds, including 56, 55, and 57 Chevys and a '57 Chevy truck. The use of minimal modifications and compatibility with both manual and power steering box is highly appreciated. Customers confirmed the high quality of the product, not only in terms of its performance but also for its look and height, providing good clearance and protection for the dist-cap. They note that it works as expected, even in engines set forward. While occasional modifications were needed, most found the product is worth its price.
