The Chevrolet 350 engine responds well to carefully chosen Edelbrock intake manifolds. This guide highlights five top Edelbrock offerings that maximize airflow, optimize torque, and maintain reliable idle characteristics for street and performance applications. Each option is evaluated for RPM range, dual-plane versus air-gap designs, and practical fitment considerations. Use this selection to match your build goals, whether you’re restoring a classic, building a hotrod, or upgrading daily driver performance.
| Product | Brand | RPM Range | Design | Notes |
|---|---|---|---|---|
| Edelbrock 2701 Performer Intake Manifold | Edelbrock | Idle–5,500 | Dual Plane | Natural aluminum finish |
| Edelbrock 7501 Performer RPM Air-Gap Intake Manifold | Edelbrock | Idle–5,500 | Air-Gap Dual Plane | Separates runners from lifter valley heat |
| Edelbrock 2703 Performer EPS Intake Manifold | Edelbrock | Idle–5,500 | EPS Dual Plane | Oil fill tube included; satin finish |
| Edelbrock 27013 Intake Manifold | Edelbrock | Idle–5,500 | Dual Plane (4150 flange) | Precise height measurements |
| Edelbrock 2601 Performer Air-Gap | Edelbrock | Idle–5,500 | Air-Gap | Patented runner tuning |
These selections emphasize a balance between performance gains and compatibility with common Chevy small-block setups from the 1955–1986 era. When assembling your engine, consider your carburetor type, chassis height, and the need for heat isolation (Air-Gap) versus straightforward street performance (Dual Plane). Each manifold listed supports Chevy small-block builds and shares Edelbrock’s reputation for durable aluminum construction and consistent vacuum signals for reliable tuning.
Edelbrock 2701 Performer Intake Manifold
The Edelbrock 2701 is a natural-finish aluminum dual-plane intake designed for small-block Chevy engines. It supports idle to 5,500 RPM, delivering broad low-end torque suitable for street performance. The dual-plane design helps with mid-range torque without sacrificing top-end performance. This model is a straightforward upgrade for users seeking a reliable, economical manifolding solution that preserves stock appearance while improving airflow over the factory intake.
Edelbrock 7501 Performer RPM Air-Gap
The 7501 RPM Air-Gap combines a dual-plane casting with Edelbrock’s Air-Gap feature, which isolates the intake runners from the heat of the lifter valley. This separation minimizes heat soak and helps maintain cooler air temperature entering the intake runners, improving throttle response and potential horsepower gains. It’s ideal for enthusiasts seeking improved performance across a broad RPM range while preserving street drivability.
Edelbrock 2703 Performer EPS Intake Manifold
The 2703 EPS model features an EPS design with an oil fill tube and breather, offering a satin finish and a fit-type for vehicle-specific applications. With an idle-to-5,500 RPM range, this manifold is suitable for customers who want a precise, modern-looking intake that fits a wide range of small-block Chevy builds and includes convenient maintenance provisions such as an oil fill tube.
Edelbrock 27013 Intake Manifold
The 27013 is a dual-plane intake with a 4150-style flange, designed for small-block Chevy applications. It lists an idle-to-5,500 RPM range and provides detailed height specifications: 3.74 inches front, 4.27 inches center, and 4.8 inches rear. This information helps builders ensure proper hood clearance and carburetor compatibility, making it a precise option for performance-focused street builds.
Edelbrock 2601 Performer Air-Gap
The 2601 is Edelbrock’s Air-Gap aluminum intake featuring patented runner tuning and an air-gap design for improved street performance. It is compatible with spread-bore or square-bore carburetors and emphasizes heat isolation to optimize throttle response and mid-range torque. This model is well-suited for drivers seeking maximum performance from a modern heat-dissipating design while maintaining broad usability with different carb setups.
Edelbrock 2101 Performer Intake Manifold
The 2101 is another aluminum, natural-finish Performer intake designed for basic street performance with an idle-to-5,500 RPM range. It features provisions to add an oil fill tube, aiding maintenance and future upgrades. This manifold appeals to builders who want a simple yet robust upgrade path for classic Chevy small-block engines.
NEWZQ Aluminum Performer EPS Intake Manifold
While not a primary Edelbrock product, the NEWZQ aluminum Performer EPS replacement for Chevy small-block engines mirrors many Edelbrock EPS features, including EPS design and a natural finish. It’s included here as a cross-reference for builders who encounter aftermarket options with similar specifications, emphasizing compatibility with small-block Chevy configurations and the importance of matching to the engine’s oil fill and breather needs.
Edelbrock 3704 Performer T.B.I. Intake Manifold
The 3704 Performer T.B.I. is designed to deliver outstanding throttle response and increased torque. It covers a broad RPM range up to 5,500 and features an aluminum plenum and base with a natural finish. Note that it may not fit certain Caprice, Buick, or Cadillac “B” bodies due to dimensional constraints, so users should verify compatibility with their chassis and carburetor setup.
Buying Guide: Key Purchase Considerations And Comparisons
- RPM range and idle behavior: Most Edelbrock manifolds listed support idle to 5,500 RPM, which suits street-to-mild performance builds. Choose a design that aligns with your typical RPM band and driving goals.
- Air-Gap vs Dual Plane: Air-Gap models (like 7501 and 2601) reduce heat soak for improved throttle response, especially in hot climates. Dual-plane designs (2701, 2703, 27013) favor broad mid-range torque and easier daily usability.
- Carburetor compatibility: Confirm bore compatibility (spread-bore vs square-bore) and flange style (4150 vs other standards) to ensure proper mounting with your carburetor.
- Heat management and breathing: Air-Gap advantages depend on engine bay conditions. If you’re running a higher-horsepower build or heavy traffic, Air-Gap can help maintain consistent air density.
- Maintenance provisions: Oil fill tubes and breather provisions (as seen on 2703 and 2101) simplify future maintenance and upgrades without requiring major modifications.
- Fitment considerations: Check hood clearance, distributor and valve-cover clearance, and vehicle-specific fitment notes (some manifolds claim compatibility or limitation with particular body styles).
- Finish and material: Aluminum with natural finishes is standard for Edelbrock; consider satin or polished finishes for aesthetics in addition to performance.
- Chassis and drivetrain alignment: When upgrading to a higher-performance intake, verify that intake height and carburetor height align with your hood, air intake, and exhaust configuration.
