Edelbrock 1103 Details

Edelbrock has decided to re-release this legendary manifold; giving a new generation a chance to own this historic benchmark. Using a pair of two barrel carburetors mounted in a "Y" configuration, this manifold unlocked the potential of Ford's versatile flathead platform for thousands of enthusiasts across the country. The Slingshot manifold is designed for use with 1938-48 style Flatheads, some late model blocks can be modified to work with these heads. It works with standard three bolt Stromberg, Holley and Demon carburetors and allows for the use of a period correct generator mounted in the stock location. 7-3/4" tall. 

This is a reproduction of the original intake manifold designed by Vic Edelbrock Sr. in 1938. The Slingshot is a real show stopper and even includes stainless acorn nuts for mounting the two halves.  Among the first ever hot rod parts, the famous Edelbrock Slingshot still ranks among the best flathead intakes out there. The Slingshot produces more peak torque than the competitors two carb intakes, as well as more overall average power and torque. The ’38-vintage, two-piece Slingshot more than holds its own even today. If you want a high-rise, Edelbrock’s design is far superior. Includes assembly hardware and gasket #8700.  

  • For 1938-48 Ford/Mercury Flathead
  • 7-3/4" tall
  • Made in the USA

Two bolt holes cannot be used by hex or Allen headed bolts unless you grind some of the intake away to clear a channel allowing the bolt to go in straight.
