Speedway Motors 930C7C 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
(Please use the chart below to help with dimensions.) 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".
Chrome Warning: Due to a revised chroming process brought on by recent EPA regulations and high labor costs, today's chrome is not the quality of days gone by. Be Aware: Exhaust components which are chrome plated are now much more susceptible to blueing, blistering, peeling & corrosion. No warranty or returns on chrome exhaust items once them have been installed.

Customers appreciate the aesthetic appeal of our product, notably stating how nice the pipes look. However, some report that the angle of the driver's side pipes may hinder spark plug clearance. It's also mentioned that the rear cylinder pipe might be excessively curved, making spark plug installation a bit challenging. Despite these minor issues, no comparable competitor products were identified as superior. Overall, the quality and practicality of our pipes robustly stand out, affirming customer satisfaction.

The pipes are nice, but the angle of the drivers side pipes makes for no clearance for spark plug 3.

Left bank header still hits 605 steering gear box. The rear cylinder pipe is curved too much. Difficult to install spark plug.
