Finding the correct auto parts for your engine can sometimes be a matter of dilemma. Your lack of proper idea about the features of the available products and price causes such a dilemma for you. If such confusion troubles your decision to buy intake manifolds, then here is a detailed review of the best intake manifolds for Chevy 350 engines.
Intake manifolds are designed as a series of tubes to route the airflow equally among the cylinders of the engine build. Their structure can be divided into two parts-plenum and the runners. The runners are the tubes ensuring fuel gets distributed to the engine evenly. The manifolds prevent overheating of the engine by cooling down the cylinders as well.
Also known as intel manifold in the world of automotive engineering, these products are traditionally made with Aluminium and cast iron. A very minor issue regarding the manifold can bring problems for your car like performance failure or overheating. Gathering some necessary prior information about them may help you tackle such aftermarket issues.

Best Intake Manifold for Chevy 350 Buying Guide
To get your engine a powerful and efficient intake manifold, you need to follow some effective handy buying tips. You have to be sure about your own priorities based on the needs of your engine and vehicles. With a detailed review of the best intake manifolds for Chevy 350, here are some smart hacks to ensure the best deal for you.
Dual or Single-plane
The difference between dual and single plan intake is in the count of open plenums – dual having two separate openings and single having one. Your decision should depend on the nature of the journeys you are going to use the engine for. If your journeys are mostly everyday street applications, dual-plane intakes are great for you. Because of the wide power range and smoother response at lower rpm, they have been loved by everyday drivers for ages.
High or Low Rise
If you are confused about high and low-rise intake manifolds, then you should know that the former one has slightly longer runners and a taller location for the carburetor(s) which usually increases torque and power compared to a “Low-rise” manifold. But you can decide in favor of a shorter manifold if hood clearance is a problem and don’t want to chop a hole in your hood.
As an owner, you must ensure that the intake you are purchasing will match the configuration, settings, model, and cylinder heads of your engine. It’s better to make a checklist of the following things before buying or ordering an intake manifold to avoid any problems later runner length or volume, plenum size or volume, carburetor setup, etc.
To understand the real efficiency of the manifolds the brands are endorsing, you need to check their rpm. Streetcars work the best when they are working with dual-plane intakes and the rpm range is “idle to 5500/6500”.
Square Bore or Spread Bore
Another selection you need to make is between square bore and speed bore intakes. The square bore contains four equally sized bores while the spread bore carries smaller primary bores and two larger bores. Different manifolds are designed for different carbs. Though usually spread bore carbs are considered to be better, still the final decision should be yours.
Though the approximate price range for intake manifolds varies between $200 -$600, still you better have a budget plan as labor costs for installing them are also going to be added later. Shortlist a number of models, keeping affordability in mind.

FAQ’s About Intake Manifold for Chevy 350
How will I know that the intake manifold of my car’s engine is out of date and I need to replace that?
When you see the following signs, you may realize that it’s time to purchase a new intake manifold for your vehicle’s engine – poor engine performance, disturbing combustion process resulting in frequent misfires, rough idle, leakage around the manifold, engine overheating and burn of an excessive amount of fuel, bad acceleration, etc.
How much does it cost to replace an intake manifold?

How much HP can be added by an intake manifold?
Usually, an intake manifold can add 5 – 15 HP though it also depends on other factors like car model, engine size, intake type, etc.
Is the camshaft important when I choose the intake manifold for my engine?
It is said by experts that the selection of intake manifolds and camshafts should go hand in hand. Usually, the camshaft mentions a range of RPM required for superior performance and there should not be much difference between the RPM rate of manifolds and camshafts.
Even if they don’t match perfectly then the acceptable difference is 500 RPM but not more than that. Otherwise, this can harm the throttle response.
What are the things I need to consider before buying an intake manifold?
With other fitment details like engine model, carburetor set-up etc. you also need to consider engine vacuum parts, water coolant ports, carburetor flange fitment, cylinder head design, etc.
