Whipple Chevy Big Block 671 Intake Manifold ONLY

Whipple Superchargers continuing strive for excellence and technological advancements continue to lead the automotive and marine markets. The ever popular GM big block based Whipple manifold is extremely modular for all different types of applications. The Whipple 671 based intake manifold works for Whipple 3.3, 4.0, 4.5, 5.0, 8.3 and all quad rotor systems. With different adapters, the manifold can also accomodate 671-1471 standard roots-type superchargers.



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 manifold features a low profile bottom that can incorporate the choice of no intercooler, standard cupronickel intercooler or the MOAC cupronickel intercooler core. The low-profile Whipple intake works with both intercooler options and features optional adapter plates for traditional 671-1471, B&M and Weiand superchargers. The 6061-T6 billet adapters feature 8" wide opening for excellent cooling and distribution while only being 1.5" tall. Maybe you want to use it with a turbo or centrifugal, just make an adapter to the 671 bolt pattern and you have a low profile intercooled manifold ready to go.



Note: Whipple 3.3, 4.0, 4.5, 5.0, 8.3 and quad rotor fuel injected applications require the 1" billet spacer for the standard intercooler to have proper distributor clearance.

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.

No thermostat housing is included, available as an option.
