An engine’s camshaft is a fundamental component. This device controls the valves. By calibrating the amount of air and fuel that enters the chamber and maintaining how efficiently the burned exhaust gas can exit, the room is prepared for the next ignition cycle.
An engine’s camshaft significantly affects its performance and is essential to its operation. With a timing chain or belt, the camshaft is connected to the crankshaft and controls the crankshaft’s movement, which is mostly moving the pistons.
THINGS TO CONSIDER BEFORE BUYING A CAM FOR 5.7 HEMI RAM
Choosing the parts for a powerful engine has a hierarchy from the most critical to the least vital. There was a philosophy among enthusiasts not too long ago, “the bigger, the better.”.
In the end, we had an over-cammed engine that sounded great and could crank ridiculous power but could not idle and wasn’t very street-friendly. Cylinder heads determine the engine’s power potential, and camshafts determine how well they work on any engine combination.
Engines depend on the camshaft they use. A machine can be made or broken by the right camshaft. A high cylinder head airflow won’t matter if the camshaft isn’t opening the valves at the right time, for the correct amount of time, or in the optimal relation to one another.
We must consider a few factors when purchasing a camshaft for the 5.7 Hemi Ram. The following are some of them.
COMPATIBILITY
When we learn how mouth-watering a camshaft’s performance is, we should check whether it is compatible with our vehicle before purchasing. Buying an incompatible came would be a waste of money.
Our camshaft must be compatible with our vehicle before we purchase it. From the specifications of our car and the information on the product’s detail page, we can do so.
PERFORMANCE
If we are looking for a specific build, we can check the camshaft’s performance rating to know the horsepower and torque it will provide. A high-end cam offers more torque, better performance, and a more comprehensive range of RPMs.
LIFT
The term refers to the displacement of the valve from its seat in the cylinder. The height of a lift is measured in inches. A lift can be classified as a Gross lift or a
Lobe lift.
A rocker ratio multiplied by a lobe lift yields a gross charge. This gives us a good ride for the valve.
At the nose of the lobe, the lobe lift is the size of the original lobe on the camshaft.
DURATION
Lifts refer to valve displacement, while durations refer to how long the cam is open in degrees of crank rotation. A duration of 0.50 inches is measured, and an advertised time is measured.

EFI applications require a camshaft explicitly tuned for them. As a result, the airflow signal to the carburetor does not have to be sent through it. The engine also performs better as a result. There is a wider separation between the lobes on this camshaft. This camshaft creates more vacuum because of its additional width.
PROS:
With 1.6:1 rocker arms, its lifts are improved without much change to the cam. This results in a broader powerband and an increase in torque, which improves the handling and drivability of the vehicle.
CONS:
The roller camshaft has low idle stalling. Modifications to the tuning will be moderate.
COMP CAMS 201-300-17 NSR HRT
The Comp cams HRT hydraulic roller camshafts are explicitly designed for HEMI engines from Gen III and IV. Due to its exclusive features, this camshaft is in the top two most effective for 5.7 Hemi Ram in our list of the finest camshafts.
This model has outstanding fuel economy due to its stage 1 NSR camshaft. Overstock produces excellent horsepower and torque without wearing down the valve springs.
As a result, valve spring replacement is minimized. Pulling a heavy load gives the engine power. Therefore, heavier vehicles will benefit from it. In addition, it has an excellent throttle response thanks to its higher torque.
With similar lobe profiles, this camshaft from HRT increases horsepower to the limit while improving stability at higher RPMs. After months of rigorous testing, HRT camshaft profiles are designed to outperform their competitors and dominate the market.
PROS:
You may want to use this camshaft if you have a more massive vehicle. It also has a very responsive throttle response, making it a competent driver. We placed it on our list for a high-performance camshaft for 5.7 Hemi because it ensures the most efficient performance regardless of engine displacement.
CONS:
It is designed for vehicles with VVT and does not work with any MDS. Additionally, it does not suit racing.
AMS-RACING VVT NON-MDS CAMSHAFT & LIFTER INSTALL KIT
You should look for the proper camshaft for a 5.7 Hemi if you want to convert an MDS engine into a non-MDS one while retaining the VVT counterpart. We have included it in our list of the highest quality cam for 5.7 Hemi ram even though it is not a ranked product.
The MDS applies oil pressure to disengage and engage valve lifters to keep the four cylinders shut off. Despite its ability to reduce oil consumption, it also has some downsides. MDS employment comes with misfires and mechanic noises. After some mileage on the system, one of the cylinders fails to deactivate. Some users can feel a transition from the regular mode to the powered-down mode, which reduces the sense of power they want.
PROS:
It combines the outstanding advantages of variable valve timing with the disadvantages of multiple displacements in one camshaft.
CONS:
To disable the MD system, we need to tune the ECU.

FREQUENTLY ASKED QUESTIONS (FAQS)
Question-HOW DOES A CAMSHAFT WORK?
Ans-A camshaft serves as a timing device. This valve controls the opening and closing of the exhaust and intake valves. Also, it determines when the valve overlaps at the top dead center (TDC) during the exhaust stroke.
Various journals are used in the construction of the shaft. Bearings within the engine support these journals. Valvetrain lobes are shaped like eggs, and these egg-shaped lobes actuate the valves. Lobes move pushrods and lifters or directly push on valve stems from actuating the valvetrain.
Question-HOW ARE CRANKSHAFTS AND CAMSHAFTS DIFFERENT?
Ans-Cast iron or steel is used to make camshafts, while alloy steel is used to make crankshafts. The camshaft is located above the cylinder, and the crankshaft is located below it, on opposite sides of the cylinder.
Question-HOW DO I KNOW WHEN MY CAMSHAFT IS GOING BAD?
Ans-Several signs can detect camshaft degradation. Below are some examples.Whenever there is an issue with the camshaft, the check engine light in our dashboard will come on. There may be other problems as well as a check engine light.
