Three Chrome 9 Super 7® Carbs to 4-Bbl Intake Manifold Adapter Kit

This tri power kit allows you to put three Elevemotors 9 Super 7® carbs on your standard 4 bbl intake manifold. It includes three carbs, the adapter, air cleaners, progressive linkage kit, fuel block, fittings and red fuel line. Assembly required. Note: Kit will NOT work with HEI distributors due to clearance issues. This system must be used in conjunction with a small diameter-based distributor. Additional Note – There are NO vacuum ports on these carbs so you may need to tap into the manifold for a vacuum source. Overall Height – 11 7/16″ total from the bottom of the adapter to the top of the air cleaners. Adapter manifold top 3×2 dimension is 4” wide by 13-11/16” long Adapter manifold is 2-3/16” tall bottom to top without the gaskets 4 barrel bolt pattern is 5-1/8” side to side and 5-5/8” front to rear 2 barrel bolt pattern is 3-1/4” side to side by 1-7/8” front to rear Progressive linkage included It does NOT come with the intake manifold to adapter gasket. 4 Barrel Carburetor Base Gasket The 9 Super 7® 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. Our 3 Carb kits come with one primary carburetor and two secondary carburetors while the 2 Carb kits are both primary carbs. See our for more information on using the 9 Super 7® in a 2×2 or 3×2 carb set-up. Three Deuce carburetor setups come with two “secondary” carbs for front and rear intake position and one “primary” carb for central/middle position 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 Primary Carb – (1) Middle Position Choke assembly, accelerator pump, and jets have all been faithfully retained and accept standard Stromberg parts Secondary Carb – (2) Front and Rear Position Special base plate with no idle circuits or choke linkage Special butterflies and shafts installed Works best with progressive linkage Idle only off the center or main carburetor No more plug foul Note: The secondary carbs have NO choke, and they have NO idle system. 9 Super 7® Primary Carbs – Features .045″ main metering jets and a number 65 power valve, which is the same as a stock 97 carb. Replacement jet access plug gasket use # 91011542, replacement needle and seat gasket use # 91011543. Includes base gasket. 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. A fuel regulator such as # 560-58500 must be utilized in order to keep proper fuel pressure at the 1-1/2 to 4 psi range.
