This kit uses the Edelbrock Slingshot intake manifold along with 9 Super 7 carbs. Kit 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.
On the primary 9 super 7 carb the throttle shaft extends from carb body .983" and has the hole on the end to pin the linkage. There is a brass sleeve that the throttle shaft rotates in that extends from the carb body .400 and this leaves the useable throttle shaft length of .583. There is sufficient room for progressive linkage and the manual throttle linkage that rotates over the sleeve.

- The 9 Super 7 ® 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.
- 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
