Here is our six-carb blower top manifold, engineered to mount six Stromberg 97 or Holley 94 two-barrel carburetors atop a GM 4-71 supercharger.
If there’s a more iconic look in traditional hot rodding than a GMC 4-71 topped with a multi-carb setup, it’s hard to find—and this is the full expression of it. Our six-carb blower top manifold is built to carry six deuces in perfect formation.
The GM 4-71 supercharger has remained a cornerstone of hot rod performance since the 1950s, originally derived from Detroit Diesel applications and quickly adopted for its durability, availability, and unmatched visual presence.
Precision cast from 356 heat-treated aluminum, this manifold maintains a low overall profile while providing proper spacing and alignment for six two-barrel carburetors using standard 5/16-18 mounting threads. Carbs are spaced 4.90" front to back, and 5.50" side to side. We cnc machine all critical surfaces for absolutely perfect fitment.
Whether you're running Stromberg 97s or Holley 94s, this plate gives you a clean, correct foundation to build your induction system around.
