Info

This kit uses Offenhauser Super Dual 1942-1948 Flathead Ford intake with 9 Super 7® carbs. It includes two carbs, the intake, air cleaners, linkage kit, fuel block, fittings and red fuel line. Assembly required. 

The 9Super7 Carb ® makes setting up a multiple carburetor induction system easier than when Strombergs were available new. All that's required to do so with our kits is a Uni-Syn syncing tool and a little patience. Be sure to include the Secondary 9 Super 7 when installing 3-carb setups. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs.  See our Multiple Carburetor Tech Tip for more information on using the 9 Super 7 in a 2x2 or 3x2 carb set-up.

  • For 1942-48 Ford Flatheads
  • 9-1/8" carb centers
  • Has boss or flange for generator or fan assembly to mount to
  • Has the fill and draft holes behind flange
  • Includes generator adapter brackets
  • All-new tooling for crisp, flawless castings
  • New aluminum base assembly allows for cooler fuel temps and better fuel efficiency as compared to the original cast iron design
  • Stainless steel screws and hardware
  • Original troublesome needle and seat replaced by a Grose-style fuel inlet valve to better cope with higher fuel pressures and improved high speed running 
  • Will not stick or dribble like the old Viton-tipped needle and seat setups
  • Extended brass throttle shaft to simplify multi-carb linkage

Notes

Manifold Specs:

  • 3-3/4" tall (measured from block mount to carb base)
  • 9-1/8" carb centers

9 Super 7® Primary Carbs -

  1. Features .045" main metering jets and a number 65 power valve, which is the same as a stock 97 carb.
  2. Replacement jet access plug gasket use # 91011542, replacement needle & seat gasket use # 91011543.
  3. Includes base gasket.
  4. The 9Super7 Carb ® will operate suitably with fuel pressures ranging from 1-1/2 psi to 4 psi, with a desired setting of 2-1/2 psi to 3 psi. Fuel pressure from 4 psi to 7 psi will cause the carburetor to run excessively rich and may cause flooding. Flooding or leaks caused by excessive fuel pressure do not indicate a faulty carburetor.
  5. Our independent tests produced these flow numbers:
    • 3" of Vacuum - 60 CFM
    • 10" of Vacuum - 110 CFM
    • 15" of Vacuum - 136 1/2 CFM
    • 28" of Vacuum - 184 CFM
