Whether you are running a Whipple supercharger, a traditional roots-style blower, or building a custom high-horsepower setup, this manifold provides a robust foundation for extreme power levels.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Cast from high-strength A356-T6 aluminum, the Whipple port-injection big block manifold is available in both standard deck (9.8\") and tall deck (10.2\") configurations. Its unique three-piece modular design incorporates a low-profile lower manifold capable of supporting either one injector per cylinder or dual injectors per cylinder, allowing precise fuel delivery for high-output and race-focused applications.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    The upper adapter features a wide 671-based bolt pattern, making it compatible with nearly any supercharger configuration from 671 through 1471. For larger blower setups, a simple 1\/2\" adapter plate reduces the opening to the standard 671 size. This same design also allows the manifold to be adapted for turbocharged or centrifugal supercharger applications using a custom adapter, resulting in a compact, low-profile intercooled intake solution.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    Whipple engineered this modular system with multiple intercooler options to support a wide range of power levels and duty cycles. The Stage 1 aluminum intercooler core measures 3.25\" thick and over 7.85\" wide, providing excellent thermal efficiency for automotive and marine applications. Dual -12AN fittings simplify coolant plumbing, while additional sensor ports at the front water passage allow easy integration of boost, temperature, and coolant sensors.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    For extreme horsepower applications, Whipple offers a Stage 2 cupronickel intercooler core measuring 5\" thick and 7.85\" wide. Featuring four internal water passages along with dual inlets and outlets, this core is designed to maintain near-ambient intake temperatures under sustained high boost. Cupronickel construction delivers exceptional strength, corrosion resistance, and longevity, technology Whipple has successfully utilized in marine environments since 2000.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n  \u003cul\u003e\n    \u003cli\u003eUniversal GM big block manifold for high-boost supercharged applications\u003c\/li\u003e\n    \u003cli\u003ePort-injected modular design supports 8 or 16 injectors\u003c\/li\u003e\n    \u003cli\u003eCompatible with 671 through 1471 blower configurations\u003c\/li\u003e\n    \u003cli\u003eWorks with Whipple, roots-style, turbo, and centrifugal supercharger setups\u003c\/li\u003e\n    \u003cli\u003eAvailable for standard deck (9.8\") and tall deck (10.2\") engines\u003c\/li\u003e\n    \u003cli\u003eThree-piece modular construction with low-profile lower manifold\u003c\/li\u003e\n    \u003cli\u003eOptional Stage 1 aluminum or Stage 2 cupronickel intercooler cores\u003c\/li\u003e\n    \u003cli\u003eDual -12AN intercooler fittings and additional front sensor ports\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n\u003cdiv\u003e\n  \u003cp\u003e\u003cstrong\u003eTHIS PRODUCT MAY BE USED \u003cu\u003eSOLELY\u003c\/u\u003e ON VEHICLES USED IN SANCTIONED COMPETITION WHICH MAY NEVER BE USED UPON A PUBLIC ROAD OR HIGHWAY.\u003c\/strong\u003e\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eLEGAL IN CALIFORNIA ONLY FOR RACING VEHICLES WHICH MAY NEVER BE USED, OR REGISTERED OR LICENSED, FOR USE UPON A HIGHWAY.\u003c\/strong\u003e\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eIT IS THE RESPONSIBILITY OF THE INSTALLER AND\/OR USER OF THIS PRODUCT TO ENSURE THAT IT IS USED IN COMPLIANCE WITH ALL APPLICABLE LAWS AND REGULATIONS.\u003c\/strong\u003e\u003c\/p\u003e\n  \u003cp\u003e\u003cstrong\u003eTHIS POLICY ONLY APPLIES TO INSTALLERS AND\/OR USERS LOCATED IN THE UNITED STATES.
