Q & A

What's in the Box

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.

  • 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".

Sorry, we do not have any notes on the small block chassis headers for the 500 series box. They do work with the 605 box and side engine mounts like our 7204175 with 91018012 and tranny mount 91628910 with 91018016. The headeris designed to fit cars using the OEM pitman arm. These headers work with most any bellhousing and most any motor mounts. Some aftermarket starters may be in the way. We offer the following measurements to help determine fit: Drivers side: Dim A is 3-1/2" by the head and 5-5/8" by the collector Dim B is 15" Dim C is 21" Pass side: Dim A is 4" by the head and 6-5/8" by the collector Dim B is 15" Dim C is 21"

These Tri-5 headers are designed for use with standard steering configurations. If running an aftermarket rack and pinion conversion as offered by Speedway you may be interested in part # 930C5 as these are specific to the Tri-5’s with rack and pinion steering. The drivers side header has specific dimensions to allow for steering shaft clearance.

Part # 930C7 These headers do not wrap inward towards the block in similar fashion as the block huggers or tight fit headers. We do offer part number 930C32 which does fit close to the block and in our catalog and on our website there are thumbnail photos that show them installed on an engine.

Part # 930C7 These headers do NOT work with angle plug heads and will not clear the stock mechanical clutch linkage. Modification of the linkage for clearance is up to the installer or you could opt for a hydraulic throw out bearing. Requires use of side engine mounts with engine in stock location and clears the standard steering gear or 605 box with the V8 pitman arm.

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.

NOTE: Stainless header tubing when exposed to exhaust temperature will cause the finish to change color which will vary with the exhaust temperature. Please note that the finish of the header when the engine is started, will change to a light champagne color to a darker gold finish and in some instance may even turn dark blue or purple. This can be polished back out when utilizing Blue-away or Simi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.
