Product Description

Holley Electric Fuel Injection Single Plane Intake Manifold with 4150 Throttle Body Flange for Chevy Small Block V8 Engines.

Holley's Single Plane Intake Manifold (300-260) is the perfect choice for your throttle body EFI system, such as the Holley 4150-style flange Universal Throttle Body. The part is optimized for high-performance street/strip Chevy Small Block V8 Engines. It offers a broad RPM powerband spanning engine speeds of 2500-7500 RPM. 

Despite accepting most stock hardware and accessory brackets, the EFI Intake Manifold features performance updates like a new-and-improved plenum divider area and a choice of two distributor clamp locations. The Intake Manifold's isolated air/fuel passages boost charge air density and performance.

Features and Benefits: 
- Single Plane Design with Isolated Plenum
- 4150 Square Bore Mounting Flange
- Powerband: 2500-7500 RPM
- Height: Front 4.18", Rear 5.28"
- Port Size: 1.92” Height 1.20" Width
- Lower Throttle Body Mounting Height Helps with Hood Clearance
- Fuel Rail Optimized for Maximum Throttle Lever Clearance

In addition, the overall Manifold height is one inch shorter than the majority of single plane manifolds. You'll also find that the fuel injector bores are designed with back-cut exits in the runners for improved fuel atomization. This strategic design points the injectors at an angle to match the intake runner airflow angle.

Holley supplies a necessary assortment of fuel rails and rail brackets, each in a black-coated finish with laser-etched logos so you can easily install the injectors of your choice.

Engine Application:
- For Use with 4150-Style Throttle Body EFI Applications
- Chevy Small Block V8 262ci-400ci 1962-1986
- Chevy Small Block 1987-Later With L98 Aluminum Corvette Cylinder Heads (Non-EGR Applications)

Tech Tip: Also, these manifolds will work with any SBC engine equipped with aftermarket cylinder heads, as long as they have a standard port flange opening and mounting bolt locations. 

Please Note: Fuel injectors are not included.
