Are you hearing strange noises from the valves of your engine? Bad camshafts can result in the improper working of the engine, loud noise from the engine as well as drop-in engine’s power.
As you know that the cams are used for intaking air for combustion in the engine as well as exhausting air after the combustion process. The valves of the engine can be opened and closed with the help of camshafts. So the selection of these camshafts must be carefully done.
For the Chevrolet 350 engine, highly specific camshafts should be used. As you can not use any kind of camshaft for any kind of engine. I will suggest some of the best cams for 350 engines with a Vortec head. Vortec cylinder head increases the efficiency of the camshafts while working. These Vortec heads are designed in a way to increase the lifting of the camshafts to open the valves.
Top Cams For 350 wIth A Vortec Head
A list of best camshafts for your 350 engine with a Vortec head are mentioned below;
1. COMP Cams 12-602-4 Big Mutha’ Thumpr
For those who are interested in street performances, this camshaft is best for their 350 Chevy engines. The idle sound that is produced by the exhaustion of the air from the combustion chamber is what makes your audience attracted to your performance. This smooth exhaustion note is due to the smooth airflow from the chambers of your engine with the help of these best Comp cams.
The shape of circular rings present on the cams determines the duration for the valve to open. The more intake and exhaustion of air would be done through the engine the better the engine would work. Those circular rings on the Comp cams are highly significant because they help to prolong the exhaustion period and help in the production of unique sound from the engine.
You need a higher stall converter of about more than 2800 to get a perfect result. Torque converters are also best to use your car as a streetcar. Its revolution range is between 2500 to 6400 Revolutions Per Minute. This small cam is more good at performance than any larger cam. You do not need to compromise on the durability or the performance of this camshaft because of its less budget.
2. Edelbrock 2102 Performer-Plus Camshaft
This camshaft is made up of cast iron and works through hydraulic lifters. These hydraulic lifters usually lift the camshaft through the hydraulic pressure inside the combustion chamber, where lots of gases or gasoline is under process. The upward and downward movements of the piston create pressure on the valve of the engine, where cams are located. This is how you get the uplifting of your camshaft.
So this camshaft’s smooth working depends upon the hydraulic lifters that lift it for intake and exhausting of the air. For smooth throttle response, this camshaft produces a high range of torque power. I found its roar to be highly smooth leaving an amazing impression on the audience while performing. It is the best choice for truck drivers, vans, motor homes, or truck campers, etc.
It is almost 14.15 pounds in weight which makes it a little heavier than other camshafts. If your vehicle’s engine has low compression, you can add the maximum torque to your engine with the help of this camshaft. No matter you have a flat top piston installed on your engine, this cam will perfectly produce high torque and power. So, do not wait and go get your best camshaft!

As it produces low torque which does not allow street performances or serious races or competitions. You can use it for daily driving as it is a 3 bolt camshaft. For 6.0L Vortec engines, this cam comes in the category of hydraulic roller cams.
Before buying camshafts, you need to know about your requirements for your vehicle. Your vehicle type, engine, your need, etc. different people use cars for different purposes. For some of them, you must be using them for racings, or street stunts, or your rides to hilly areas or deserts but some of them use them simply on the road. If you can narrow down your needs, you can easily buy the best camshaft.
1. Engine Type
One major thing you need to know before buying a camshaft for your car is its engine. You must take any professional’s suggestion about the type of camshaft you need for a specific type of your car’s engine. The up-mentioned camshafts are best for the Chevy 350 engine, which is usually a small block. According to your car’s model, this engine uses horsepower of almost between 145 to 370.
By keeping the engine in your mind, you would see whether the cams are suitable for it or not. As some engines need more camshafts than usual dual overhead cams. For Example, the W engine of Bugatti Veyron needs four camshafts, to push 64 valves. So, the quad cams would be needed there. Hence, before buying a camshaft you must keep the engine model in your mind.
To buy a camshaft, the type of camshaft matters a lot. Different types of camshafts are used for different purposes. There are hydraulic flat tappet cams, solid flat tappet cams, hydraulic roller cams, etc. and they are used for different purposes. If you are interested in street performances, then my suggestion to you would be hydraulic flat cams while solid rollers should be used for serious races.
So as a Chevy 350 engine owner, you must be looking for the best camshafts which are above mentioned. As Chevy has a small block engine so the cams that you use would not be suitable for heavy engines. You do not need hydraulic or solid roller cams for the best working of your engine. So go for different types of cams according to your needs.
Maintenance of any auto part is highly required if you wish to keep using it for a longer period. No matter which type of camshaft you are buying, every part needs care. Some of them need high care while others need lesser care. You must get a camshaft that can easily be maintained by you. As per my experience, hydraulic roller camshafts can easily be maintained with no extra care.
Solid roller camshafts are the cams that need more maintenance. So, accordingly, whatever camshaft you are buying, you must be aware of its required maintenance. If it needs high maintenance you can take the help of any professional or if not much maintenance then you can handle it yourself. These cams are one of the basic parts of any engine that help in closing or opening the valve of the engine. If you don’t maintain it properly you can face serious problems.
The size of the camshaft also matters. If you have small engines then the cam used in it would also be small. For bigger engines, bigger cams would be needed. It does not mean that if you are buying a big size of the cam then it would give you perfect results. You may notice over time that the result you needed can not be gained through your big camshaft. Hence, knowing the size appropriate for your engine is also necessary.
How big a cam can I used for Vortec’s head?
Cams can be used with Vortec heads used on engines. These sealing heads allow 0.42 and 0.47 inches lift of the cams. This is the approximate limit the cam can lift for Vortec heads. You should not use any bigger cam for a Vortec head because a simple cam can easily be fit for the engine using a Vortec head. So there is no need for you to worry about the size of a cam if you are using Vortec heads on combustion cylinders.
Summing It Up
To sum it all up, some of the best cams for 350 with Vortec head engines are mentioned above. All of these cams are specifically used for one or the other type of engine. My best picks among all these mentioned cams are given below;
COMP Cams 12-602-4 Big Mutha’ Thumpr is one of the best cams that is highly compatible with a Chevy 350 engine with a Vortec head. Its high sound is the result of intake or the exhaustion of the air inside the combustion chamber. You can use them for various street performances.
Edelbrock 2102 Performer-Plus Camshaft, is used for mild or less powered engines which are more preferred by daily truck drivers. These cams are not suitable for races or competitions. Otherwise, they are easy to install and perform greatly.
Lunati 10120102LK Bare Bones Hydraulic Flat Cam is the perfect choice for races and competitions. They produce 2300 of high torque which mounts the performance of your car in the race with high sound.
I found out that different cams are used for different purposes. Some are best for races or competitions while some are used for daily drivings. But all these cams are compatible with 350 Vortec head engines. You can easily install them on your truck or racing car and enjoy your drive smoothly. High-power-producing cams are more suggestive for producing loud and thunderous sounds to add life to the performance.
