Speedway Motors 9300570S Details

Give your street rod a nostalgia look and help uncork its performance potential with these lakester headers for big-block Chevy V8s. The lakester header works great on early hoodless and fenderless rods like T-buckets, Model A's and 1932-1934 Fords. Vertical flanges allow you to connect the lake style headers to a muffled under-car exhaust when the end plates are on.

  • Fits 396-502 B/B Chevy
  • Hookups provided for under-chassis exhaust (2-1/2" O.D.)
  • Block-off plate allows you to easily uncork headers
  • 1-7/8" primaries, 4" collectors

NOTE: Turn-outs NOT included. Headers come with end plates, but the turn outs are sold separately.

  • 1-7/8" primary tube diameter
  • 4" collector cone diameter
  • 2-1/2" O.D. street lead down tube diameter

Use the illustration below with these measurements:

  • A = 4-1/2"
  • B = 2-1/2"
  • C = 27"
  • D = 12-1/2"
  • E = 6-1/2"

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 utilizingBlue-awayorSimi-chrome polish, but please note that when the headers reach running temperature again, they will immediately change color.

Overall Assessment

Customers highly appreciate the asthetically pleasing, polished finish and superior welding quality of the headers. They find them to be of excellent manufacture, offering value for their cost in comparison to other brands. A minor concern is the position of the header's outlet, as they slightly point inward. Nevertheless, the product receives strong recommendations for its overall appeal and craftsmanship, particularly for T-Bucket enthusiasts.

These look great. Great looking welds. The outlet on the bottom of the header is slightly pointed in towards the car. I wish it pointed straight down. Other than that, I love em.

Very pleased with this purchase. The quality of manufacture and the polished finish all exceeded my expectations. These aren't cheap but the price, compared to some other brands, and combined with quality, ends up being a really good deal, in my opinion. I would definitely recommend these, they look great on my T Bucket.
