Tri-Power Intake Manifold
Z3x2 intake manifolds are the first bolt-on tri-power
intake system designed specifically with Holley carbs
for small block Chevy heads.
They'll fit all 23° Chevy heads from 1955 thru 1986.
With two 325 cfm outboard carbs and a 350 cfm center
carb, Z3x2 manifolds deliver head-snapping acceleration
and performance. Punch it and see!
And with progressive linkage, you can cruise all day on
just the center carb and still get excellent gas mileage.
