What's in the Box

Info

Classic Chevy owners will love these big block V8 chassis headers for 1955-1957 cars.  They have 34"-36" primary tubes for lots of power, but they're tucked close to the body for maximum ground clearance.  The manufacturer says that they won't work with manual transmissions due to clutch linkage issues!  These headers are finished with our Armor Hot Coating.

  • Quality steel construction
  • Mid-length design offers maximum ground clearance, even if car is lowered 4"

 

Application

  • Fits automatic transmissions
  • The manufacturer says that they won't work with manual transmissions due to clutch linkage issues!
  • Designed to work with 605 power steering box
  • Will not work if engine is set forward more than 3/4" for firewall/HEI distributor clearance
  • Won't fit tall-deck (truck) blocks
  • Needs aftermarket side mounts and a rear trans crossmember (rather than stock bellhousing mounts)

Notes

Armor Hot Coating (AHC) is a heat resistant, ceramic coating applied to the outside of the header. This coating will reflect heat, which helps retain more heat within the header tube while simultaneously speeding up the exhaust flow. Not only will this coating help you make more horsepower, it also keeps your headers rust-free, looking great, and lasting longer (when properly maintained).  If you are looking for a show-quality finish for your headers, this is it! Our AHC will withstand exhaust temperatures of up to 1300¢ª F. 

Warranties

These headers do not fit angle-plug heads. The manufacturer says they will not work with 168-tooth flywheels or with some aftermarket-style starters. They will not work on side-style engine mount conversions that move the engine forward for distributor clearance.

AHC Warning: AHC coatings will burn and be damaged at exhaust temperatures over 1300 degrees. A lean fuel mixture can generate exhaust temperatures exceeding 1700-1900 degrees. If the coating is damaged due to a lean condition, the coating will not be warranted, but can be recoated for a fee.

Not legal for sale or use in California on pollution controlled vehicles

Looks Great! - Can't Wait!

December 23, 2015
With the price I figured I'll be happy with them, you know ... for the price. Didn't have high expectations. Speedway came through on these headers! I couldn't believe how heavy gauge steel is used on the tubes and on the flange. They are way better than my old name brand headers. Had a test fit and things look good. Can't wait to try them out! Keep in mind the warning about not fitting with the 168 tooth flywheel/flexplate, it's not the plate it doesn't clear, it's the starter in that position. I'm going to try a certain brand high torque mini starter and see if it clears. If it doesn't, then I'll dent 1 tube. My old name brand headers I had to dent 4 tubes much worse than these. They look great too, I can't wait for the final installation and of course the testing! A very happy customer!
Yes, I recommend this product.

Quality is way up there!

December 20, 2015
I haven't had the chance to run these yet so I can't comment on performance, even when it is up and running, I'm doing other engine mods so won't be able to comment on the header performance with so many different variables. The greatest thing about it is the heavy gauge tubes and flange. I don't know what gauge the tubes are but from looking into the collector, they are much heavier than the Hookers they are replacing. They tuck up high after removing the frame horns. WAY BETTER than the Hooker super competition that gave me only 3.25" road clearance at over factory height. The one very misleading thing is in the description. It says it won't work with a 168 tooth flywheel? Well how the heck would it hit that without hitting the turbo400 tranny? The answer is that they will hit *the starter* when using the larger flex plate. And by the looks of it, I think I can get a small starter that will clear. If not I'll hammer it in a little. These are just too good for the price!
Pros:
  • Inexpensive
  • Quality Construction
Yes, I recommend this product.

55-57 BBC headers

November 15, 2015
They look great! The fit is just ok. I had to dent multiple tubes on both sides for clearance. I even ordered the recommended motor mounts from Speedway. I also had to clearance the firewall. Overall they worked and look good.
Yes, I recommend this product.

Great Parts that work well!

May 13, 2014
These headers work very well in my 1955 Chevy, Big Block, The vehicle has rack and pinion steering, side mounts (standard location) They do require the removal of the frame horns for the bell housing style stock mounts. I used the rear crossmember and side mounts anyway! These headers allow your car to sit as low as you would want as the headers and exhaust are tucked right up next to the frame!
Yes, I recommend this product.

These headers will work with a factory steering box or the 605 power steering box. They will not work with stock clutch linkage or tall deck truck blocks. You must have side motor mounts and rear transmission mount installed. Also the motor cannot be slid ahead more than ¾" for firewall clearance. Dimensions of the headers are as follows: Drivers Side Dimension A: 10.10 Drivers Side Dimension B: 13.00 Drivers Side Dimension C: 35.38 Passenger Side Dimension A: 9.90 Passenger Side Dimension B: 14.35 Passenger Side Dimension C: 41.13 Collector Length: 5.75
