EVIL ENERGY LS1 LS2 LS6 Single Plane Carburetor Intake Manifold

EVIL ENERGY LS Single Plane Carburetor Intake Manifold

The EVIL ENERGY LS single plane intake manifold is designed for compatible GM LS1, LS2, and LS6 cathedral port engines using a carbureted fuel system. This LS carburetor intake manifold uses a cast aluminum single plane layout with a listed 5000-7500+ RPM operating range, making it suitable for high-RPM LS builds, drag applications, track-day platforms, and performance-focused LS swaps when the full engine combination supports that range.

Unlike a dual plane LS intake manifold that is usually chosen for low-to-mid RPM street response, a single plane intake manifold uses a shared plenum and shorter, more direct runner layout. This design is commonly selected when the build goal is upper-RPM airflow, larger camshaft support, high-speed acceleration, or a carbureted LS setup that prioritizes top-end performance over low-RPM cruising torque.

Important: Always confirm cylinder head port shape, carburetor compatibility, hood clearance, throttle linkage, fuel system setup, ignition controller needs, intake gasket style, and bolt pattern before ordering. This manifold is intended for LS1/LS2/LS6 style cathedral port cylinder heads, not LS3/L92/L99/L76 rectangular port heads.

Vehicle and Engine Fitment

This EVIL ENERGY LS intake manifold is designed for GM LS Gen III or Gen IV engines equipped with LS1, LS2, or LS6 style cathedral port cylinder heads. Common reference applications include Chevrolet Corvette C5, Chevrolet Camaro, Pontiac Firebird / Trans Am, Cadillac CTS-V, Holden Monaro, Holden Commodore, Holden HSV, Pontiac GTO, Chevrolet SSR, and compatible LS-swapped platforms.

Vehicle names are provided as reference examples only. Engine swaps, cylinder head changes, carburetor selection, ignition control, throttle cable routing, fuel pressure regulation, hood clearance, and accessory clearance can affect final fitment. Always verify that your engine uses cathedral port LS cylinder heads before installation.

Key Features - EVIL ENERGY LS Single Plane Intake Manifold

• LS1/LS2/LS6 Cathedral Port Fitment: Designed for compatible GM LS Gen III or Gen IV engines using LS1, LS2, or LS6 style cathedral port cylinder heads.
• Single Plane High-RPM Layout: The shared plenum and direct runner design support upper-RPM airflow for builds focused on high-speed performance rather than low-RPM-only drivability.
• 5000-7500+ RPM Operating Range: Built for LS combinations where the camshaft, cylinder heads, exhaust, carburetor, ignition setup, and gearing support a higher operating range.
• Carburetor-Ready LS Conversion: A practical option for builders replacing an EFI-style intake setup with a carburetor intake manifold on a compatible cathedral port LS engine.
• Cast Aluminum Construction: The cast aluminum body provides a durable intake platform for high-RPM LS carburetor builds, street/strip projects, and track-focused applications.
• Boosted Build Compatible When Properly Matched: This single plane layout may be used in turbocharged or supercharged LS combinations when the carburetor, fuel system, ignition control, and tuning strategy are matched to the build.

Package Contents and Installation Checklist

Before Installation, Check These Items

• Confirm that your engine uses LS1/LS2/LS6 style cathedral port cylinder heads.
• Do not use this manifold on LS3/L92/L99/L76 rectangular port heads unless your engine has compatible cathedral port heads installed.
• Confirm carburetor size, mounting pattern, throttle linkage, throttle cable bracket, fuel line routing, and air cleaner clearance.
• Carbureted LS conversions may require a compatible ignition controller, fuel pressure regulator, carburetor linkage parts, and other supporting components depending on the build.
• Check hood clearance, brake booster clearance, firewall clearance, accessory bracket clearance, vacuum ports, and PCV routing.
• Use suitable intake gaskets and follow the proper torque sequence during installation.
• High-RPM intake changes may require tuning, gearing, camshaft, exhaust, and fuel system support to work as intended.

Why Choose This LS Single Plane Intake Manifold?

This LS single plane intake manifold is designed for builders who want a carburetor-ready intake option for compatible cathedral port LS engines and a higher operating RPM range. For many high-RPM LS builds, airflow demand, camshaft profile, cylinder head flow, carburetor sizing, ignition control, exhaust setup, and gearing all matter when choosing the right manifold.

For Corvette, Camaro, Firebird, GTO, CTS-V, Holden, Chevrolet SSR, or LS-swapped projects using compatible LS1/LS2/LS6 cathedral port heads, this EVIL ENERGY LS engine intake manifold provides a focused option for high-RPM carbureted LS applications. Final results depend on the full engine combination, carburetor size, camshaft, exhaust, ignition timing, fuel system, tuning, and installation quality.

FAQ

Q: What engines does this LS single plane intake manifold fit?
A: This intake manifold is designed for compatible GM LS Gen III or Gen IV engines equipped with LS1, LS2, or LS6 style cathedral port cylinder heads. Always confirm your cylinder head port shape before ordering.

Q: Will this fit LS3 heads?
A: No. LS3/L92/L99/L76 style engines commonly use rectangular port heads, while this manifold is intended for LS1/LS2/LS6 style cathedral port heads.

Q: Is this a carburetor intake manifold?
A: Yes. This is a single plane LS carburetor intake manifold designed for compatible carbureted LS applications.

Q: What RPM range is this manifold designed for?
A: The listed operating range is 5000-7500+ RPM. Actual performance depends on the camshaft, cylinder heads, carburetor, exhaust, fuel system, ignition setup, gearing, and tuning.

Q: Is a single plane intake better than a dual plane intake?
A: It depends on the engine combination and driving goal. A single plane intake is commonly chosen for higher RPM airflow, while a dual plane intake is often preferred for low-to-mid RPM street response.

Q: Is this a good choice for daily street driving?
A: It depends on the build. Because this is a high-RPM single plane intake manifold, it may not be ideal for users who prioritize low-RPM cruising torque. A dual plane LS intake manifold is often better for street-focused low-to-mid RPM drivability.

Q: What should I check before buying?
A: Check cylinder head port shape, carburetor compatibility, hood clearance, throttle linkage, ignition controller requirements, fuel system setup, gasket style, bolt pattern, and supporting engine modifications before ordering.
