Whipple Chevy Big Block Port-Injected Intake Manifold ONLY

There are many options available for Whipple Supercharger kits. If you have any questions please email sales@TREperformance.com or call 760-586-5617.

Cast from A356-T6, these unique manifolds are offered in both standard deck (9.8") and tall deck (10.2") versions. Featuring a unique 3-piece design, the Whipple port-injection manifold features a low profile bottom that can incorporate 1 injector per cylinder or 2 injectors per cylinder giving you the ability to make whatever power your engine can produce. The upper adapter is made with a wide opening, 671 based bolt pattern meaning it can fit nearly any application. Maybe your looking to upgrade a Whipple 3.3L, 4.0L, 4.5L, Quad Rotor or 8.3L to port injection? For 671-1471 applications, a simple 1/2" plate necks down the opening to the standard 671 opening of 4" wide. Maybe you want to use it with a turbo or centrifugal, just make an adpater to the 671 bolt pattern and you have a low profile intercooled manifold ready to go.

Whipple designed this modular based package with multiple intercooler options. The Stage 1 coated aluminum core that measures 3.25" thick and over 7.85" wide for maximum cooling with its superior surface area works with auto and marine applications. The intercooler features dual 12AN fittings for simple in/out plumbing. The manifold is equipped with extra sensor ports at the front water passage as well as extra boost and temperature ports for easy setup.

For even more power, Whipple offers the new Stage 2 Cupronickel intercooler core that is 5" thick and 7.85" wide for maximum cooling at all boost levels. With the added volume, the core features a total of four water passages. Dual inlets and dual outlets help pass enough water to maintain near ambient temps. Whipple brought the nearly indestructible Cupronickel cores to the marine in 2000 and continue to utilize its incredible cooling properties while never corroding in even the harshest water conditions.
