Z3x2 Tri-Power Intake Manifolds & Holley carburetor systems for Small Block Chevy's.

Fits 1955 – 1986 Small Blocks

Nothing looks better than three deuces perched on top of a small block. It just defines the classic street rod.

And now you can get great looking performance with a complete bolt-on package from MultiCarbs!

Z3x2 Intake Manifolds

Z3x2 has teamed up with MultiCarbs to bring you the ultimate in Holley tri-power performance. Systems fit all standard 23° Small Block Chevy heads.

  • Z3x2 dual plane medium rise intake manifold
  • 3 Holley 2-bbl carbs  (Two 325 cfm carbs on either end, one 350 cfm center carb w/electric choke)
  • Stainless steel fuel rails
  • Progressive throttle linkage
  • K&N style air filters with chrome housings
  • Intake manifold gaskets

Z3x2 Manifolds are made from high quality permanent mold castings with CNC machined surfaces and smooth rounded internal surfaces for unrestricted airflow.

Economy and Big Horsepower  

Cruise around economically on the 350 cfm center carb, and when you decide to step on it, the two 325 cfm outboard carbs kick in for head snapping performance!

Dyno Tested Performance

We tested the Z3x2 with a 350 cu. in small block with a stock cam. Compared with a typical 4-BBL setup, the Z3x2 delivers more horsepower at lower rpm– 346 hp at 5200 rpm compared with 337 hp at 5400 rpm with the 4-BBL. A Z3x2 gets up early and stays late!
