Speedway Motors 9300575 Details

Nostalgia-style street rods are hotter than ever, and nothing gives your vintage rod that authentic dry lakes competition look like a set of lakester headers. These small-block Ford lake style headers work great on early hoodless and fenderless rods like T-buckets, Model A's, and 1932-1934 Fords. Each lakester header has vertical flanges so you can connect it to a muffled under-car exhaust when the end plate is on.

  • Fits most SBF 289-351W heads as well as GT40 type "P" heads
  • Hookups provided for under-chassis exhaust
  • Block-off plate allows you to easily uncork headers
  • 1-5/8" primary tube diameter
  • 3-1/2" collector cone diameter

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