What's in the Box

Info

These fender well headers provide the ultimate performance for 396-502 big block Chevy V8s in 1955-57 Chevy car applications. They kick up over the frame rail and exit just at the bottom of the cowl, which makes them perfect for Gasser-style rods and drag cars. Plus, these headers feature long primary tubes that help produce more horsepower and torque than shorter, more compact headers.

These headers are not for the faint of heart since you must cut the inner fender panels to make them fit, and tire clearance can be a problem on some applications. They may require smaller front tires to avoid contact. The stock emergency brake rod must also be altered. Can be used with most oil filter systems or transmission and starter combinations. The headers are designed to be used with engines in the stock location, not lowered as many kits do, so all '55-'57 cars should check motor mount positioning before ordering.

  • Header flange has 1-13/16” x 1-13/16" port size
  • Will require fender well cutting or alteration
  • High temp black paint finish
  • Includes bolts and gaskets
  • Note: This header actually goes upward from the head instead of down before dropping over the frame rails. From the top of the head flange to the top of the tubes is approximately 9-1/2".

Notes

  1. These are universal-fit fenderwell steel tube headers for big block Chevy V8 engines. They will require cutting and altering inner fender panels. Tire clearance can be a problem on some applications. May require smaller front tires to avoid contact.
  2. Designed to be used with engine in stock location (relative to stock 1955-57 Chevy transmission position), not lowered as many kits do.
  3. The stock 1955-57 Chevy emergency brake rod must be altered. You may also have to modify your emergency brake cable.
  4. Can be used with most oil filter systems or transmission and starter combinations.
  5. This header actually goes upward from the head instead of down before dropping over the frame rails. From the top of the head flange to the top of the tubes is approximately 9-1/2".

A good fit

August 19, 2014
I went out on a limb for the fit (a custom installation, big chevy in a 65 nova)The headers were just what I expected, a good fit, well made, and one complete kit. I needed nothing else for the installation, all gaskets, and bolts were furnished as well as the collectors. Thanks, I will do business again. Mike Vigueria

These are obviously not made for that application. You may want to start by comparing the dimensional info to the space available in your engine bay/fenderwell area. Then if they seem like they could possibly fit you could give them a try. We accept returns on headers as long as they are in like new and re-sellable condition. Once they have been installed and the engine started they are not returnable.

These particular headers are made to fit the 55-57 cars. They may work for your truck but there is going to need to be fabrication and creativity to do something like that. I haven't heard of anybody trying this.

Part # 930C4 Depending on engine location and setback or set forward these headers may fill your needs. These headers go up first right after leaving the head approximately 91/2” to the top of the tubes. The A dimension from the top of the flange to the furthest out point of the collector is only 25 ¼”. The B dimension from the top of the flange to the bottom of the collector is only 5 ½” and from the front of the flange to the furthest back of the collector is 29 ¾”. With those dimensions and some mock up measurements you can verify fit on your vehicle.

Part # 930C4 Speedway does not have a full listing of all the vehicles these fender well headers would fit. We do have some dimensions that with some basic measurements you may be able to verify fit to your application. 1) From the top of the header flange to the top of the tubes is 9 ½”. The tubes curve sharply upward after leaving the head and reach the 9 ½” at the top of the tubes before turning outward. From here they go outward and then drop down behind the front wheels. From the head surface outward to the end of the collector is 25 ¼”, from the top of the flange to the bottom of the collector at it’s lowest point is only 5 ½”, and from the front of the flange to the furthest back point of the collector is 29 ¾”. These dimensions along with the photo of the headers and some basic measuring should determine fit.

These fenderwell headers for the Big Block Chevies work on many applications but for verification of preferred fit on your application we recommend some basic measurements be taken. The headers go up from the head 91/2” first before going outward and over the frame rails. From head outward to the furthest point of the collector is 25 ¼”, top of header flange to bottom on the collector is 5 ½”, and from front of the header flange to rear of the collector is 29 ¾”. In some applications and depending on engine location the collector may end up close to the firewall or body mount. Some basic measurements will help eliminate questions on fit.

Speedway part number 930C4. These headers will fit many different applications. I do not have a listing that tells me they will fit a 66 Nova, but if you take some measurements that will help determine if you can use these. The width of header at widest point from exhaust port - 25-1/4" Height of header from top of flange to lowest point - 5-1/2" Length of header from front of flange to collector - 29-3/4" Tube size - 2" Collector size - 3-1/2"
