EVIL ENERGY Chevy Big Block Hurricane Oval Port Intake Manifold

EVIL ENERGY Chevy Big Block Hurricane Oval Port Intake Manifold

If your Big Block Chevy build is limited by an older intake, a mismatched carburetor setup, or airflow demand above the normal street RPM range, the EVIL ENERGY BBC oval port intake manifold gives builders a carburetor-ready option for compatible 396, 402, 427, and 454 engines. Its 4,000-6,500+ RPM range is aimed at drag builds, high-RPM street machines, and performance BBC projects where the full engine combination supports upper-RPM use.

This Big Block Chevy intake manifold is designed for compatible oval port BBC cylinder head applications. It is a practical option for builders replacing older intake hardware, planning a carburetor intake manifold swap, or choosing a 454 intake manifold, 427 intake manifold, or 396 intake manifold for a performance-focused Chevrolet big block project.

Important: Always verify engine family, oval port cylinder head compatibility, intake bolt pattern, carburetor mounting pattern, intake gasket style, hood clearance, throttle linkage, fuel line routing, and port alignment before ordering. This manifold is intended for compatible Big Block Chevy oval port applications and should not be assumed to fit Small Block Chevy, GM LS, or rectangular port BBC combinations.

Vehicle and Engine Fitment

This Chevy Big Block intake manifold is designed for compatible 1965-2000 BBC 396, 402, 427, and 454 V8 engines using oval port cylinder heads.

Vehicle names are provided as reference examples only. Engine swaps, cylinder head changes, oval port versus rectangular port differences, carburetor selection, air cleaner height, throttle linkage, accessory clearance, and hood clearance can affect final fitment. Before installation, confirm that your engine and cylinder heads match this BBC intake manifold.
