Pontiac V8 Intake Manifolds

The Haytalras 7156 is a high-rise dual-plane intake manifold with a 4150 square-bore carburetor flange for 1965–1979 Pontiac V8 engines: 326, 350, 389, 400, 421, 428 and 455. The dual-plane layout keeps strong street torque, and the higher plenum supports more top-end power.

Our V8 intake manifolds are cast and CNC-machined in our own factory, then checked for air-tightness, dimensions and finish before they are packed. Orders ship within 24 hours on business days from our warehouses in Ontario, California and Bloomingdale, Georgia.

FAQ

Does one intake fit every Pontiac V8 from 326 to 455?

Pontiac V8s from 326 to 455 share the same external dimensions, so the 7156 is listed for all of them from 1965 to 1979. Check hood clearance, since it is a high-rise design.

What carburetor does it take?

A 4-barrel square-bore (4150-style) carburetor. A Quadrajet needs a spread-bore adapter.
