Buying Considerations of Best Intake Manifold For Chevy 350
As discussed earlier in the product review, dual-plane intake manifolds, such as Edelbrock 2701, deliver excellent power from idle through the 5,500 rpm range.
You need a buying guide to help you make an informed decision on your intake manifold choice.
What are other considerations to make while buying intake manifolds?
These three steps will guide you to make the right choice today:
01. Choose your choice (Dual-Plane, Single-Plane, or Others)
You’ll find intake manifolds in various styles such as dual-plane, single-plane, tunnel ram, and so on. The choice is yours, but you should make the right choice based on your vehicle’s intake style and proposed rpm operating range.
Dual-plane intake manifolds come in two separate openings, which allow air or fuel from the carburetor. Each of the openings flows into four cylinders on a V8 engine.
This sectionalized design ensures that each cylinder sees every other firing pulse, reducing the chance of overlap between induction pulses which further results in a much smoother induction pulse, notably at low rpm.
Also, they typically possess extended intake runners, which makes them a great option for low and medium-range power production.
Here are the following reasons to choose a dual-plane manifold:
- Low rpm response and power within the range of 1,500-6,500 rpm
- Impressive idle quality
- For mild racing and street performance.
Among our reviewed products, the Edelbrock Performer is one of the best dual-plane intake manifold options.
One of the major differences between a dual-plane and single-plane intake manifold is the number of open plenum. While the former has two openings, the latter has one opening, which supplies all eight cylinders on a V8 engine.
Unlike the dual-plane, which has a smooth induction pulse in low range rpm, it generally allows better and equally distributed flow between cylinders.
Likewise, it has shorter and more-direct runners, which allows it to move a large volume of air from the carburetor to the heads.
Here are the following reasons to choose a single-plane manifold:
- High rpm response and power within the range of 8000 rpm
- Ideal for racing events
Check out these single-plane intakes:
Although most of the products reviewed are dual-plane, the single-plane intake manifold options are also common.
As mentioned earlier, we have other intake styles aside from the dual-plane and single-plane, which are the commonest.
Other options include Air-Gap intake manifolds and the Tunnel ram intake manifold. Some of our reviewed products also fall into these categories.
02. Find the Right fit
Once you have made your choice of intake manifold style, your next task is to choose the manifold that fits rightly with your application.
Here are some considerations to make while shopping for your ideal intake manifold:
- Hood clearance
- Cylinder head port design
- Carburetor body mounting
Hood clearance is one aspect to consider, especially for street applications.
If you intend to retain your hood, measure your stock manifold height and look for a similar intake manifold measurement.
A higher intake manifold can be accommodated through a hood scoop, air cleaner, or other means. Note that all these will take more time and you will also spend more money.
It is also imperative to take note of cylinder head port design. There are big block Chevy heads with several port designs, including oval, rectangular, and nut-shaped.
Always ensure the ports for intake runners are a perfect match with your cylinder heads.
Similarly, you should ensure your new intake manifold works perfectly well with your carb mounting pad configuration.
For instance, four-barrel carbs come with three basic mounting pads, namely:
Spread bore, square bore, and Dominator style. Check for the type of mounting pad used by your carburetor and ensure the intake purchased is in tandem with it.
If you choose to buy a fuel injection manifold, ensure you check the throttle body inlet to ascertain that it fits your throttle body size perfectly.
03. Fine Tune Your Choice
Now you have made your choice on the intake style you want. All is verified and in perfect shape and condition.
But, here is the final step to take before you get the much desired green light.
If you reside in an area with special emissions regulations—here is a must for you to read. Consult a certified intake manifold professional to help check out your intake manifold for adherence to regulations.
You can also make a comparison of port cross-section, plenum volume, and check the length of the runner to throttle down your choice.
We hope these three points will help you make the right consideration regarding your intake manifold choice.
The Common FAQs of Best Intake Manifold For Chevy 350
How to choose my desired intake manifold?
Intake manifolds aim to allow more air and fuel passage from the carburetor into the cylinder heads.
If you want your Chevy 350 to perform optimally, you should choose a dual-plane manifold with two chambers to receive the mixture of air and fuel from the carburetor.
The air-fuel mixture from each chamber is delivered to each four-cylinder row in a V8 motor.
How much HP does an Edelbrock intake manifold add?
According to the product specifications, the Edelbrock Performer intake manifold could add between 5 to 10 HP.
Is it possible for a 305 intake manifold to fit into a 350?
You cannot differentiate between the 305 and 350 intake manifold except the sticker placed on the cover because it’s the same block.
The holes for the 305 and 350 are identical. So, ensure you pay attention to both before mounting.
How to Get More HP from My Chevy 350?
It’s quite easy to add more horsepower to the Chevy 350 motor. Here are a few steps to get more horsepower out of your Chevy 350 motor:
Change and adjust your air intake. You can achieve this in various ways, like installing a K & N air filter or an entire cold-air-intake system.
The latter comes at a higher price but gives better results in terms of horsepower gain.
The amount of horsepower generated depends on the amount of cool air your motor can take in. It would be a wise decision to modify your air intake based on your desired horsepower gain.
Adjust your exhaust. After successfully adjusting and increasing air intake, that air must find a place to leave the engine.
There are a few exhaust options available such as dual exhaust, headers, and pipe diameter increase of about 3 inches.
Headers allow your motor to exhale as it is designed to produce a back pressure for your motor, invariably increasing horsepower. However, a dual exhaust does a better job in horsepower gain.
Replace your valve train and camshafts. It is inexpensive to increase horsepower by modifying the valve train.
Get a new cylinder head or polish the existing one. Some companies configure cylinder heads to improve performance and increase horsepower.
Through this configuration, fuel and airflow are improved using bigger valves with intake and exhaust ports.
Do you need to torque your intake manifold?
The idea is not to make the bolts too tight till it cracks or goes out of sequence. The intake manifold doesn’t need that much torque.
How can I Detect Intake Manifold Leaks?
There are two major ways leakage could occur with the intake manifold. The coolant leaks out, or external air leaks into the manifold without passing through the designated passageway.
Engine performance can be affected through air leaks, while engine failure can occur from coolant leaks.
Check intake manifold side where tubes are attached to the engine. Check for coolant leak signs in the form of wet spots.
You could note the severity of the leak from the amount of wetness observed.
Put coolant leak test dye in your radiator cap. Change the cap, and ignite the engine till it completely warms up.
After, please switch off the engine to allow it to cool off before working on the engine. Wear protective goggles and flash UV light around the areas where the leak is detected earlier.
You will see a bright green color wherever a leak is detected, representing the dye in the coolant.
To detect a leak in the intake manifold gasket, start the engine and spray the carburetor cleaner through its nozzle.
Wait a while to observe changes in the engine speed; if it speeds off or changes the way it runs, it implies that you leak.
What are the noticeable signs of a faulty intake manifold gasket?
The intake manifold gasket usually shows few signs when it gets bad or faulty, which indicates a need for replacement.
1. Decreased acceleration, power, and fuel economy coupled with an engine misfire
When the intake manifold gasket becomes bad, one of the noticeable signs is engine performance. Wear and tear occur to the intake manifold gasket as your vehicle increase mileage, thereby causing performance issues.
2. Coolant leaks
Leakage of coolants is another sign of bad intake manifold gasket which needs to be addressed as soon as noticed.
3. Engine overheating
The overheating of the engine overheating is another sign of faulty intake manifold gaskets.
If you notice any of the signs mentioned above, you should consult a professional technician for assistance.
How much torque does a 350 have?
The Chevy 350 has a rating of about 380 lb per ft of torque which is superb for towing; however, it consumes more fuel which may necessitate the need for premium fuel depending on its compression ratio.
The Chevy 350 is GM’s best-known small-block V8 engine and considered one of the world’s best engines.
It is very durable, reliable, versatile, and offers great performance wherever it’s used. It has a torque rating of about 380 lb-ft, which is ideal for towing.
However, depending on the compression ratio, it has a low fuel economy, and you might need to use premium fuel.
