This tri power kit uses the Edelbrock C-357-B S/B Chevy 3×2 intake with Speedway’s 9 Super 7® carbs. It has progressive linkage to give you good driveability and economy, but power when you need it. The manifold has a balanced 180° firing order port runner arrangement. It contains an exhaust gas heat riser and offers excellent performance potential. (idle-5500 rpm)
Kit includes three chrome plated carbs, the plain finish aluminum intake, 4″ chrome air cleaners, linkage kit, chrome fuel block, fittings and red fuel line. Assembly required. Fits 1955-1986 Chevy 262-400 c.i.d. small-block Chevys.
Note: Not applicable to an HEI based distributor system due to a clearance issue. This system must be used in conjunction with a small diameter based distributor.
The 9 Super 7® 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.
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
The original troublesome needle and seat were replaced by a Grose-style fuel inlet valve to better cope with higher fuel pressures and improve 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.
