EVIL ENERGY SBC 4150 Single Plane EFI Intake Manifold with Fuel Rails

EVIL ENERGY SBC 4150 Single Plane EFI Intake Manifold with Fuel Rails

If your Small Block Chevy EFI build needs more upper-RPM airflow than a street dual plane intake can support, the EVIL ENERGY SBC 4150 EFI intake manifold gives builders a single plane option with fuel rails for compatible 262-400 cid SBC engines. Its 3500-8000+ RPM range is aimed at high-RPM street/strip builds, larger-displacement combinations, turbo or supercharged setups, and EFI projects where the camshaft, cylinder heads, fuel system, and tuning support higher airflow demand.

This single plane intake manifold uses a large shared plenum and short runner layout for compatible Small Block Chevy EFI combinations that prioritize upper-RPM airflow. It is a practical option for builders replacing older intake hardware, planning an EFI intake manifold upgrade, or choosing a 4150 intake manifold with fuel rails for a performance-focused SBC project.

Important: Always verify engine family, cylinder head configuration, intake bolt pattern, EFI system layout, injector length, fuel rail fittings, sensor placement, hood clearance, throttle linkage, fuel line routing, and port alignment before ordering. This manifold is intended for compatible Small Block Chevy applications and should not be assumed to fit Big Block Chevy, GM LS, or unrelated engine families.

Vehicle and Engine Fitment

This Small Block Chevy EFI intake manifold is designed for compatible 1957-86 262-400 cid Small Block Chevrolet engines, including 262, 265, 283, 302, 305, 307, 327, 350 small block, and 400 cid applications. It also supports SBC engines equipped with 1987-91 L98 aluminum Corvette cylinder heads for non-EGR applications.

Common reference applications include Chevrolet Corvette, Camaro, Nova, Impala, Monte Carlo, El Camino, Caprice, C/K Series Pickup, Suburban, Blazer, GMC light trucks and SUVs, and select GM small block platforms. Vehicle names are provided as reference examples only. Engine swaps, cylinder head changes, EFI system selection, injector setup, air cleaner or throttle body height, accessory clearance, and hood clearance can affect final fitment.

Key Features - EVIL ENERGY SBC EFI Intake Manifold

Package Contents and Installation Checklist

Before Installation, Check These Items

• Confirm that your engine is a compatible Small Block Chevy 262-400 cid application.
• Verify cylinder head configuration, intake port alignment, bolt pattern, and gasket compatibility.
• Confirm EFI system layout, throttle body or 4150-style setup, injector length, injector O-ring style, and fuel rail fitting requirements.
• Check fuel line routing, regulator setup, fuel pressure requirements, MAP/IAT sensor placement, vacuum ports, and PCV routing.
• Check hood clearance, throttle linkage, accessory bracket clearance, distributor clearance, and surrounding engine-bay space.
• Do not assume compatibility with Big Block Chevy engines, GM LS engines, or unrelated engine families.
• Use suitable intake gaskets and follow the proper torque sequence during installation.
• EFI intake manifold changes may require ECU calibration or tuning adjustments depending on the build.

Why Choose This SBC 4150 EFI Intake Manifold?

This SBC 4150 single plane EFI intake manifold is designed for builders who want an EFI-ready intake option for compatible Small Block Chevy engines with a higher operating RPM range. For many SBC performance builds, airflow demand, camshaft profile, cylinder head flow, injector compatibility, fuel rail setup, ECU control, exhaust, and gearing all matter when choosing the right manifold.

For Corvette, Camaro, Nova, Chevelle, C/K truck, Suburban, Blazer, or custom Small Block Chevy projects using compatible 262, 305, 327, 350, or 400 cid engines, this EVIL ENERGY EFI intake manifold provides a focused intake solution for high-RPM street/strip, boosted, and performance EFI applications. Final results depend on the full engine combination, injector selection, fuel system, camshaft, exhaust, ignition timing, ECU tuning, and installation quality.
