Things to Consider Before Buying Best Cam For 350 With Vortec Heads

As you already know, the camshaft is the engines’ “brain” and it is responsible for controlling the operation of a cars’ intake and exhaust valves.

Needless to say, choosing the perfect camshaft for your model and engine directly impacts horsepower, torque, and idle quality, among others.

Also, if you are looking to build a capable and powerful engine there is a need to be familiar with the hierarchy of parts involved.

However, no matter your choice of these parts, whether they be top of the line, they would be rendered useless and inoperable if your choice of the cam is incorrect.

The camshaft, as a brain, orchestrates proper connection among various other parts of the engine.

While it is true that a good choice of cylinder head determines your engines’ maximum power potential, the camshaft would still determine if they will go along with your well-synchronized engine.

Camshafts also happen to be a very complicated subject that borders closely on equally tricky Physics, should you want to really understand the science behind it.

Regardless, the very first step before actually choosing a new cam is to understand the different camshaft lobe components.

This may sound like hard work but it will significantly make the process of selecting faster and easier to comprehend, thus helping you make a very sound decision in the end.

Understanding the basics and their applications is fundamental in choosing your next camshaft.

Before Starting

This may seem like a very basic question considering you are already in the process of buying a new camshaft but you have to ask yourself next: What really is this engine for?

You can say it is for better performance but a lot of car owners do not really have an idea what this upgrade is specifically for and this almost always results in dissatisfaction on the customer’s end.

Knowing exactly what you want and what you are doing it for, lays down the most specific and the most important factor: What will the car be used for most of the time.

One expert says the worst thing to happen to your engine is to over-cam it.

Making sure that the lift, lobe separation angle, and duration are in sync with each other to make sure your engine works to its full potential.

Additionally, this consideration will also make sure that the engine will work properly with the car itself.

Like everything else, all parts must work together in harmony. Before getting any work done, someone who is considering this upgrade should be realistic with his/her expectations.

Camshafts should be your final consideration

In order to make sure you are getting the optimal results, your choice of camshaft should be made last, and not the other way around.

This is a common mistake. It is more preferable to build a cam around the engine and not vice versa. The reason is quite simple.

The internal combustion engine is technically just an explosion of the air pump brought about by the opening of the valves.

And these valves’ capacity to remain open is dependent on the airflow potential of the engine.

Types of Camshaft

Camshafts have 4 basic types namely: hydraulic flat tappet, hydraulic roller, solid flat tappet, and the solid roller.

Each specification is usually found in the cam card which is included in the camshaft package. Below is the overview of each camshaft spec.

Basic RPM Range

  • This is the scope or the engines’ peak performance. Upon choosing a camshaft, try to find one with an RPM range that perfectly matches the other parts of your car and its usage purpose.

Lift

  • This refers to the distance of the valve from the cylinder and measured in inches. It basically implies how tall are the cam lobes.

Duration

  • Measured in degrees by the rotation of the crankshaft, the duration is the amount of time the valve remains open. It informs the width of the cam lobes. In layman’s terms, a “bigger cam” means a cam with more duration.

Lobe Separation Angle (LSA)

  • This is the distance of the centerline point of intake and exhaust lobes which is also measured in degrees of camshaft rotation. The lobe separation angle works out how the lobes are related to each other on the cylinder.

After all, these factors are considered and one has already decided what camshaft to purchase, properly installing it is the next crucial step.

Proper installation is directly relevant to the engine’s top performance. Poor installation could lead to power loss and even damage, in extreme cases.

Frequently Asked Questions (FAQ) About The Best Cam For 350 With Vortec Heads

Q1: Do I really have to replace my camshaft?

A: It makes sense to find a replacement for a camshaft especially if the one that you have is worn out and obsolete.

Damaged camshafts also need to be replaced in order to make sure your engine and car stay at the top of their game.

Camshafts should improve your engines’ performance and not power them down. It is important to do your research before even considering a change.

Q2: Which cam is perfect for my car?

A: This is ultimately decided based on your cars’ capacity to take air in and out because this is what camshafts are all about.

It is necessary to look around and gather information before jumping the gun. All engines are created differently and so are people’s opinions.

It would be an advantage to research the different effects of various cams before finalizing a decision.

Q3: How much horsepower gain can I get?

A: There is no exact way to know this and give an accurate number.

There are just many engine components to take into account such as the exhaust system, the ratio of compression, porting, carb size, etc.

The safe guess involving a stock engine would be around 10% percent.

Q4: How do you recognize a bad engine camshaft?

A: There are several ways to do this. The first one is by revving up the engine and listening for a rhythmic ‘pop’ sound or any other bad noise.

Another way is to completely remove the cover of the valve and observe the cam movement. Visually checking the camshaft for wear and tear also works.

Q5: Does a camshaft make the car noisy?

A: If it makes an unpleasant noise then it is high time to check if everything still works well.

Camshafts are movable components of the engine and they may cause noise for a number of reasons.

If it runs out of oil and gets overheated, it may make clunking sounds. The noise could also be caused by loose parts banging against each other.

It is best to have your car checked in case this happens.

Q6: What damages a camshaft?

A: Most of the time, this is caused by some parts becoming loose and hitting it like the connecting rod.

Sometimes the damage is caused by a crack or fractures even only after a short time of use and installation.

This would likely be caused by poor shipping handling or improper installation.

Q7: Can I use old lifters with a new camshaft?

A: An old lifter and a new cam should never be paired. It is possible to use new lifters on new camshafts though.

Lifters have specific ‘partner’ lobes and this cannot be changed. It is better to discard used lifters and buy new sets, then do the cam break-in once again.

Q8: What is lobe wear?

A: This usually happens because of inappropriate lubrication during the installation process.

The rule of thumb is to use manufacturer lubricants (which are often included in the camshaft package).

The correct and proper way of applying the lubricant is every surface of the cam lobe and the bottom of every tappet cam.

Q9: Should I use a flat tappet or roller camshaft?

A: This would depend on what kind of engine you are looking to build.

If you are going for a high revving engine, then a flat tappet camshaft with solid lifters will provide you with the best RPM rates.

On the downside, the solid lifters can cause noise and thus require adjustments from time to time.

For an engine with the best torque power, the combination of roller cams and hydraulic lifters are preferable. It is the most ideal choice for street performance and low RPM.

Conclusion

All in all, there are a number of criteria to determine a camshaft replacement.

Matching the camshaft to your vehicle and engine is important to get satisfactory results.

Proper understanding of the camshaft system is also imperative in order to make a good choice of the camshaft.

It may not be easy to understand all the cam components at first but the knowledge you get about it will prove to be useful in choosing the best cam for your engine.
