The intake manifold is the single biggest bolt-on decision you make on a Chevy 350. It controls where your torque lives, how your engine breathes at every RPM, and whether your small block feels lazy at a stoplight or wakes up when you stand on it. Pick a single-plane race intake for a mild street 350 and you will lose low-end grunt. Pick a tired stock cast-iron intake for a built motor and you will choke off the top end. The right manifold matches your camshaft, your carb or throttle body, and how you actually drive.
We compared the most popular Chevy 350 intakes that buyers actually search for and bolt on, looking at dual-plane versus single-plane design, hood clearance, carburetor pad size, and how each one behaves on a real street car. Below are seven manifolds that genuinely fit the small block Chevy, ranked best first, with the honest weaknesses of each so you can match one to your build instead of guessing.

1. Edelbrock Performer RPM Air-Gap 7501 SBC Intake Manifold: Best Overall
If you want one intake that does almost everything right on a street and strip 350, this is the one to beat. The Performer RPM Air-Gap takes the proven dual-plane design and lifts the runners off the lifter valley with an open floor, so heat from the oil down below does not soak into your incoming air. The result is a denser charge, a cooler running manifold, and a powerband that pulls cleanly from just off idle all the way past 6000 RPM. On a typical 350 with a performance cam, headers, and a matched carb, it delivers the kind of midrange punch that actually shows up when you drive the car, not just on a dyno sheet.
The honest tradeoff is height and heat. The Air-Gap sits taller than a Performer or a stock intake, so before you buy you should measure your hood clearance, especially with a drop-base air cleaner. The same open floor that keeps things cool also means the engine takes a little longer to warm up in cold climates, and on a carbureted setup that can mean a slightly longer choke cycle on freezing mornings. For most builders those are minor prices to pay for the best all-around performance on this list.
- Air-Gap runner design separates the intake floor from the hot lifter valley for a cooler, denser charge
- Dual-plane layout keeps strong low and midrange torque while still pulling hard up top
- Fits standard square-bore carbs and clears most aftermarket valve covers and air cleaners
Pros: Excellent broad powerband that suits a cammed street 350 perfectly; Cooler intake charge from the Air-Gap floor adds real measurable power; Crisp throttle response and strong vacuum for street manners
Cons: Taller than a stock intake, so hood clearance can be tight under low hoods; The open floor lets the manifold warm up more slowly on very cold mornings
2. Edelbrock Performer EPS 2701 SBC Intake Manifold: Best for Daily Driving
For a stock or lightly modified 350 that lives on the street, the Performer EPS is the sensible, no-drama choice. It is a dual-plane manifold tuned for the bottom end and midrange, which is exactly where a daily driver spends its life. You get a rock-steady idle, strong off-the-line torque for towing or just pulling away from a light, and clean part-throttle manners that make the car pleasant to drive every day. Its low-profile design is a real selling point because it slips under tight factory hoods where a taller intake simply will not fit.
The catch is that this manifold is deliberately not built to chase top-end horsepower. Above roughly 5500 RPM it starts to sign off, so if your build includes a healthy cam, big valve heads, and a desire to rev, you will leave power on the table. Think of the EPS as the right answer for a clean, reliable street 350 rather than a performance project, and it will reward you with reliability and easy fitment that the hotter intakes cannot match.
- Low-profile dual-plane casting clears stock and low hoods with room to spare
- Tuned for strong street torque from idle through the midrange
- Bolts on with stock-style accessories and works great with a 600 to 650 CFM carb
Pros: Outstanding low-end torque and a smooth, steady idle; Short height fits under almost any hood without modification; Easy bolt-on for a stock or mildly modified 350
Cons: Runs out of breath up top compared to an Air-Gap or single-plane intake; Not the best match for a big cam or a high-RPM build
3. Weiand Stealth 8017 SBC Intake Manifold: Best Value
The Weiand Stealth is the manifold I point people to when they want most of the performance of a premium dual-plane without paying for the name on the box. Its raised, well-shaped runners give a 350 a genuinely wide powerband, with strong torque down low and a willingness to keep pulling into the upper midrange. On a typical street build with a cam, decent heads, and a 600 to 700 CFM carb, it wakes the engine up noticeably over a stock intake while keeping the idle smooth enough for around-town driving and a reasonable hood profile.
Where it falls a little short is at the very top. It does not have the cool-charge advantage of an Air-Gap floor, so the last few hundred RPM and the peak horsepower number trail the more expensive picks here. The casting finish is also a touch coarser than Edelbrock’s, though that is cosmetic and does not affect how it runs. For the money, it remains one of the smartest performance intakes you can bolt onto a small block Chevy.
- Stealth dual-plane port design delivers a wide street powerband
- Compatible with stock-style hood clearance and standard accessories
- Works well with cams up to a moderate street and strip grind
Pros: Strong all-around performance that competes with pricier intakes; Good idle quality and street manners for a performance dual-plane; Quality casting with clean ports right out of the box
Cons: Top-end pull is a step behind the Air-Gap design; Finish is a bit rougher than the premium Edelbrock castings
4. Edelbrock Performer 2101 SBC Intake Manifold: Best for Stock Rebuilds
The plain Performer 2101 is the manifold for the builder doing a faithful, reliable rebuild of a stock or near-stock 350. It is the original Performer dual-plane that earned Edelbrock its reputation, and it does exactly what it promises, which is to replace a heavy, possibly cracked factory cast-iron intake with a lighter aluminum casting that idles smoothly and responds crisply to the throttle. For a truck, a cruiser, or a restoration that needs dependable street performance rather than maximum power, it is a safe and proven choice.
The flip side of that dependability is that it is not a power adder on a stock engine. If your heads, cam, and exhaust are all factory, you will mostly gain weight savings and a cleaner casting rather than a big jump on the dyno. It is also a non-EGR design, so check your local emissions requirements before ordering if your vehicle still needs to pass inspection. Used as intended on a sensible street rebuild, it is hard to fault.
- Classic Performer dual-plane design proven on millions of small blocks
- Replaces a tired or cracked stock cast-iron intake with a lighter aluminum unit
- Smooth idle and improved throttle response over a factory manifold
Pros: Reliable, predictable upgrade over a worn stock intake; Lightweight aluminum saves weight over cast iron; Broad availability and simple bolt-on installation
Cons: Modest gains if your engine is otherwise completely stock; Non-EGR design may not suit some emissions-regulated applications
5. Edelbrock Victor Jr 2975 SBC Intake Manifold: Best for High RPM
When the goal is peak horsepower and the engine is built to rev, the Victor Jr is the intake that delivers. This is a single-plane, open-plenum race manifold with tall, straight runners that feed every cylinder evenly when the tach is swinging hard. Bolt it to a 350 with a big solid or hydraulic roller cam, ported heads, and a healthy carburetor, and it rewards you with the kind of upper-RPM pull that a dual-plane simply cannot make. Bracket racers and street-strip builders have trusted this casting for years for exactly that reason.
The honest weakness is everything below the powerband. A single-plane intake sacrifices low-end torque and idle quality to make that top-end power, so on a mild or stock 350 it will feel lazy off the line, idle rougher, and drink fuel for little reward. This is not a manifold to buy because it looks fast on paper. It only makes sense if the rest of your engine is built to use the RPM it is designed for, in which case it is one of the best in its class.
- Single-plane open-plenum design built for serious top-end power
- Tall, straight runners feed all eight cylinders evenly at high RPM
- Ideal partner for big cams, ported heads, and a large carburetor
Pros: Massive top-end horsepower on a built, high-revving 350; Even cylinder filling for consistent, repeatable power; A favorite of bracket racers and high-output street builds
Cons: Soft low-end torque and a rougher idle make it poor for daily driving; Needs a matched big cam and carb to perform, so it punishes mild builds
6. Weiand Action Plus 8501 SBC Intake Manifold: Best for Street Torque
The Weiand Action Plus is all about the bottom end, and that makes it a smart pick for a 350 that needs to move weight. Its low-rise dual-plane design is tuned for low and midrange torque, the part of the curve that matters when you are towing a trailer, hauling a heavy truck, or just want strong, immediate response off the line. The low height is a bonus for builders fighting hood clearance, and it works happily with stock or mildly worked heads and a sensible street cam.
What you trade away is the top of the tach. Like other torque-focused low-rise intakes, the Action Plus signs off earlier than a high-rise or Air-Gap manifold, so a high-RPM build will outgrow it. The idle and overall refinement are also a notch below Edelbrock’s premium pieces. But if your priority is real-world pulling power and easy fitment rather than peak horsepower, this manifold gives you exactly that at a value that is hard to argue with.
- Low-rise dual-plane tuned hard for low and midrange torque
- Generous hood clearance for tight engine bays
- Pairs well with stock heads and a moderate cam
Pros: Excellent grunt for towing, trucks, and heavy cruisers; Compact height fits under low hoods easily; Strong, usable performance on a budget-minded street build
Cons: Limited top-end compared to a high-rise or Air-Gap intake; Idle and refinement trail the premium Edelbrock castings
7. Speedmaster PCE148 SBC Dual-Plane Intake Manifold: Best Budget Pick
For builders on a tight budget who still want an aluminum dual-plane, the Speedmaster PCE148 is a workable option. It follows the familiar dual-plane layout that works so well on a street small block, gives you a usable powerband from idle into the midrange, and saves a meaningful chunk of weight over a stock cast-iron intake. For a mild 350 in a project car or daily driver where every dollar counts, it gets the basic job done and accepts the same common square-bore carbs as the premium manifolds.
The reason it sits at the bottom of this list is consistency. Quality control on budget castings is not on the level of Edelbrock or Weiand, so it is worth inspecting the ports, checking the carb pad for flatness, and test-fitting your gaskets before you torque everything down. Spend a little time on that prep and it can serve a budget build well. Skip it and you risk small fitment or sealing headaches that the more expensive intakes simply do not have.
- Affordable aluminum dual-plane styled after the proven performer layout
- Lightweight replacement for a heavy stock cast-iron intake
- Square-bore pad accepts common street carburetors
Pros: Strong value for a complete aluminum dual-plane manifold; Decent street powerband for a mild 350; Light and easy to handle during installation
Cons: Casting and machining quality are less consistent than name-brand intakes; May need port cleanup or a careful gasket check before final install
Frequently Asked Questions
Should I run a single-plane or dual-plane intake on my Chevy 350?
For the vast majority of street-driven 350s, a dual-plane intake is the right call. The split-plenum design gives you strong low-end and midrange torque, a smooth idle, and good drivability, which is exactly what you want for a car you drive on the road. A single-plane intake like the Victor Jr only makes sense if your engine is built to rev, with a big cam, ported heads, and a large carb, and you are chasing peak horsepower at high RPM. On a mild or stock 350, a single-plane will feel soft off the line and idle rougher for little real-world gain, so unless you are racing, stick with a dual-plane.
What is the benefit of an Air-Gap intake manifold?
An Air-Gap manifold has an open floor that physically separates the intake runners from the hot lifter valley below. That gap stops engine oil heat from soaking into your incoming air charge, so the air stays cooler and denser, and a denser charge makes more power. On a 350 you can feel and measure the difference, especially under sustained driving when a conventional intake heat-soaks. The tradeoffs are that an Air-Gap intake sits taller, so you need to confirm hood clearance, and it warms up a little more slowly on cold mornings. For most performance street builds the cooler charge is well worth those minor downsides.
Will these intake manifolds fit any Chevy 350 small block?
These manifolds are designed for the Gen I small block Chevy, which covers the classic 350 along with the 305, 327, and 400 sharing that bolt pattern. The key thing to confirm is your cylinder head style. Most of these intakes are built for standard non-Vortec heads with the older square intake port and bolt angle. If your engine has factory Vortec heads from the mid-1990s on, you need a Vortec-specific intake because the port shape and the bolt pattern are different. Always match the manifold to your heads, and check whether your build requires EGR provisions before ordering.
What size carburetor should I run with these intakes?
For a typical street 350 with a dual-plane intake, a carburetor in the 600 to 650 CFM range is the sweet spot and gives crisp response with good fuel economy. A hotter build with a performance cam and better heads can use a 650 to 750 CFM carb, and the Performer RPM Air-Gap or Weiand Stealth will happily feed it. The single-plane Victor Jr is built for larger carbs, often 750 CFM or more, because it is meant for high RPM. Resist the urge to overcarb a mild engine, since too much carb on a street 350 hurts throttle response and drivability more than it helps.
Do I need a new intake gasket and what should I watch for during install?
Yes, always install a fresh intake gasket set and never reuse the old one, because a leaking intake gasket causes vacuum leaks, rough idle, and even coolant problems. Match the gasket port size to your heads, clean both the head and manifold sealing surfaces thoroughly, and check the carb pad and runner ports for flatness, especially on budget castings. Many builders skip the factory end-rail cork seals and lay a bead of RTV silicone across the front and rear China walls instead, which seals more reliably. Torque the manifold bolts in the proper crossing sequence and in steps to the spec for your gasket to avoid leaks and distortion.
Our Verdict
For nearly every street and strip Chevy 350, the Edelbrock Performer RPM Air-Gap 7501 is our top pick, because its cooler intake charge and wide dual-plane powerband give you strong torque and real top-end pull in one bolt-on, as long as you have the hood clearance for it. If you want maximum drivability under a tight stock hood or you are building a clean daily driver, the Edelbrock Performer EPS 2701 is the runner up, trading some top-end for a low profile, a smooth idle, and excellent street manners. Match the manifold to your cam, heads, and how you actually drive, and your small block will reward you every time you touch the throttle.
