- Not a performance cam
If you are willing to enhance the performance of your automobile, probably due to daily driving experiences, lesser frequenting of gas stations, or to brace yourself against inconsistent weather conditions, picking the right camshaft should be a step to consider.
The camshaft intended to be bought should be able to regulate the airflow and amount of fuel that goes into the cylinder, impacting the performance of the engine.
Camshafts comprise various lobes which shut and open the valves.
However, before picking up the best performance parts for 4.3 Vortec from any vendor’s shelf, the various levels of lift, daily workability of the engine, and compatibility with the engine type, amongst others, should be closely scrutinized.
In any attempt to replace or install the 4.3 Vortec performance mods, the first step is to ensure that the camshaft is most compatible with the engine.
This is because cams either improve or decrease the performance of an engine.
Irrespective of the airflow allowance from the cylinder head, if the valve refuses to open at the right time and for the appropriate period, the engine might be at risk.
When the lift, lobe separation angle, and duration are not matched with the true end purpose, it might lead to an over-cam, which is worse than under-camming.
When a driver does not intend to spin hard often, there shouldn’t be any reason to build a high rpm engine.
The cam should work harmoniously with the engine, as compatibility is the key to an automobile’s lasting and overall performance.
When choosing a camshaft, a flat tappet or roller cams are likely preferences one might have to carefully deliberate upon.
Flat tappets come with a slightly curved base and a lifter, while roller cams come in the form of a roller and with lifters.
OEMs use roller cams for their engines because it produces more mid-range and top-end power when compared with the power produced by flat tappet cams.
03. Gross Lift
Another point of consideration, when faced with getting a new camshaft, is the gross or camshaft lift.
It specifies the degree to which the valve is moved from its seat by the cam lobe.
The higher the valve is lifted from the seat, the more the unit of rotational speed is around a fixed axis.
However, there can be cases of lesser airflow if the lift of the camshaft gets too high.
This might lead to an increase in turbulence since the air will break away from the surface of the valve.
The gross lift should never be too low, as too little airflow will lead to lesser engine power.
The period the camshaft will keep the valve off the seat should be a consideration if a buyer is really serious about getting the best cam for 4.3 Vortec.
The degree of crank rotation, together with the period of gross lift are factors that determines the total proportion of the open valve.
The duration of these camshafts ranges from 220°-280°.
However, 280 degrees have often been exceeded on several occasions.
Rougher idle, however, occurs when there is a higher power range due to the cases of longer duration.
A cam capable of making 240 degrees duration can produce 3000 – 7000 rpm, which might be what a buyer may have always wanted.
05. Lobe separation
This area can be found between the intake lobe points of the camshaft and the peak lift exhaust.
The lobe separation is usually measured in degrees.
The lobe separation details the intake valves’ activities to the cylinder’s exhaust valves.
Low to mid-range torque production occurs when a camshaft’s narrow lobe is present.
The narrow lobe separation often ranges from 104 -108 degrees.
However, it will also increase the cylinder pressure, reduce idle vacuum, and make the engine idle worse.
The narrowness of the separation can be as low as zero degrees.
Although this is not advised, the intake and the exhaust valves would begin to flip open and close, thus making it unable to function properly.
Furthermore, if the lobe separation is between the range of 112 – 116 degrees, there will be a reduction of pressure on the cylinder, which will make the idle vacuum very smooth and lessen the issue of overlap between the intake and exhaust valves.
A wider lobe separation will allow for a higher rpm, which can lower the torque production and narrow the engine operational region.
The last point anyone will love to consider when attempting a 4.3L Vortec performance upgrade is the process of installation.
Instead of fusing several engines and hoping for a better outcome, the camshaft should be degreed to be perfectly timed to the crankshaft.
The length of the timing chain, the bottom gear dot positioning, perfect phasing of lobes to the dowel pin, and the bottom gear key-way positioning, among others, are issues that might derail the engine off the right track if not properly calculated at the point of purchase.
The easiest way to degree the camshaft is when the engine is on an engine stand.
Feel free to follow this videoto learn how to easily degree your camshaft.
How Does A Camshaft Work?
Since the main function of a camshaft is to reciprocate the motion of a converted rotary motion of the filter, this allows the engine to experience fuel discharge and traction through the regulated opening and closing of the exhaust valves.
The camshaft enables the piston to pass its energy to the crankshaft which receives it and transforms it into a rotary force, thus commencing rotation.
As the crankshaft is connected to the camshaft either through the belt of gear, it sends motion to the camshaft, transforming it into a reciprocating motion that puts pressure on the inlet valve to open it.
At the opening of the valve, fuel is allowed into the combustion chamber.
Friction and compression strokes create a combined air-fuel mixture that expands the chamber, forcing the piston’s downward movement.
Motion gets received again as the piston moves downward and gets collected by the camshaft.
Conclusively, as the exhaust valve’s cam receives the motion, the exhaust valve is pressed and opened.
At this point, the exhaust gasses can move out of the combustion chamber.
Can Big Cams Be Used For Vortec’s Head?
Once the sealing head is capable of 0.42 – 0.47 inches lift of cams, it can be used with the Vortec head engines, as that is the limit of cam lift for Vortec heads.
Bigger cams should not be considered because cams can be easily fixed for Vortec head engines due to the presence of combustion cylinders.
The Lunati 10180702k bare-bones hydraulic flat cam is a 4.3 Vortec camshaft capable of producing as much as 2300 quality high torque, which gives the automobile a high sound and swift racing performance.
Its high power production, together with its thunderous sound, adds life to the vehicle’s overall performance.
How Do I Know If My Camshaft Is Bad?
- Delayed Acceleration: A camshaft can be said to be bad when acceleration is delayed. This delay often occurs due to a miscalculation or dragged reaction from the camshaft.
- Engine Light: the engine warning light on your dashboard may be triggered if the automobile is experiencing a problem. It is advised that should the engine indicator continue blinking, the vehicle should be turned off as soon as possible and must not be moved at all. Although this light might be triggered for many reasons, a mechanic should remain the first person to contact.
- Poor Fuel Management: When a camshaft position sensor is wearing out, it will be unable to accurately read data to the engine’s control module. This will hinder the smooth running of the automobile and cause the vehicle to consume more fuel.
- Improper Transmission Shifting: You can know if your camshaft is wearing out when the energy transmission is being barred from shifting normally due to the error data sent to the engine control module. Once this issue occurs in some vehicles, the automobile switches into limp mode, which is a security feature that prevents the engine from being damaged.
- Increased Emissions: The poor performance of a camshaft can cause the vehicle to experience a cloudy exhaust. This could result from the engine’s inability to burn fuel efficiently.
- When the car doesn’t start: Although this might be due to a bad starter kick, when weak signals are sent to the engine control module due to the camshaft position sensor failure, the vehicle might be unable to start too.
- Rough-idling Engine: A failing camshaft can cause the vehicle to idle roughly. When the engine was running and left to idle for a while before it is engaged, the idling should be smooth if the camshaft is properly functioning. The inability of the engine to idle smoothly can be sensed as a measurement misappropriation from the cylinder.
- Stalling: The pace at which a vehicle moves could sometimes be slower than the gear selected. When this happens, it results from delivering a specific amount of fuel by the fuel injector. The reason for this can be traced to the camshaft’s performance, and a replacement should be considered.
- Fuel Pollution: When the smell of raw fuel is noticed to be oozing from the tailpipe, it might be due to the poor performance of the camshaft. Sensitive drivers might want to take note of these simple symptoms to be able to save their automobiles before things get messy.
What Is The Most Common Reason Why Camshafts Wear Out?
Lack of proper lubrication.
For any camshaft to operate normally, it must be properly oiled.
If the increased friction caused by the rotation of the camshaft is left unaddressed, it will eventually cause the oil passages to get blocked or give room for too much clearance.
This can end up spoiling the bearings and the cam cap due to a high concentration of heat and friction which will be generated.
Therefore the portion between the pin and the roller and the lobe and the roller must be properly lubricated to reduce friction and wear components.
How Do I Reset My Camshaft Timing?
Getting the best performance cam for 4.3 Vortec is no child’s play.
Fixing it is another experience while setting its timing looks somewhat tricky too.
In short, camshaft timing is the timing of the vehicle’s engine.
It details the expulsion and intake of exhaust fumes by the camshaft.
The opening and closing of some cylinder valves at some specified period are called timing.
At the rotation of the camshaft, the lobes will put pressure on the valves, which will open up the valve.
As the camshaft rotation releases the pressure applied to the valve, the springs on the valves close them immediately.
This regulated opening and closing of the valves can be harmed by wear and tear, thus warranting the camshaft timing to be reset or adjusted to enhance and maintain the engine’s overall performance.
Step I: The first step to individually reset the camshaft timing is to read the car engine manual.
This will aid in locating the camshaft easily when the hood has been propped.
Step II: The distributor in the vehicle should be carefully loosened with the aid of a wrench.
After that, the timing mark must be determined probably with a piece of chalk to indicate the TDC (top dead center) on the harmonic balancer.
Step III: After marking, the car battery and the lead spark plug must be connected with the timing light, while the car should be started afterward.
When the car starts, the timing light on the harmonic balancer should be checked, along with the timing belt and the timing mark on it.
Step IV: The chalk mark on the cylinder can determine the camshaft timing.
The position of the top cylinder is called the top dead center, while the piston will need to be steadied at zero degrees on the rotation cycle.
However, should the cylinder not be in this position, the timing can be manually adjusted if the distributor is being moved.
Step V: After steps I-IV have been properly executed, the car engine should be shut, while the distributor should be carefully tightened with the aid of a wrench.
You can watch this video if you require more guidance to reset your camshaft timing.
The overall compatibility and functionality of the Lunati 10180702k voodoo make it the best cam for 4.3 Vortec.
The smooth, easy experience when the vehicle is being started, the ability for the vehicle to idle smoothly, and the superb engine sound are factors to be considered when deciding to purchase a camshaft.
We are sure you will be able to choose the suitable cam for your 4.3 Vortec engine.

According to our BrandZoom™ Camshafts report, based on surveys of automotive enthusiasts who have shopped for or purchased a cam, the top 3 camshaft brands that are most trusted are COMP Cams, Crower and Edelbrock (in alphabetical order). Each of these three had a 90% or higher positive perception.Does a bigger cam need more timing? ›
The bigger the camshaft, the more it really needs part-throttle timing at low engine speeds.What happens if cam timing is advanced? ›
Advancing or retarding a camshaft's timing from its original "zero" position causes the valve events to happen either earlier or later in the engine's cycle. A camshaft that is advanced four degrees will cause each opening and closing event to occur four degrees of rotation sooner than before.What turns faster crank or cam? ›
Because one turn of the camshaft completes the valve operation for an entire cycle of the engine and the four-stroke-cycle engine makes two crankshaft revolutions to complete one cycle, the camshaft turns half as fast as the crankshaft.What makes a cam lope at idle? ›
Again, keeping all else constant, more duration will make the engine less efficient at low rpm, with more overlap dilution of the induction charge, and the later intake valve closing reducing the trapping efficiency. Therefore, a long-duration cam will cause rough running at idle (lope) and a loss of low-rpm torque.
Generally its because the aftermarket camshaft (s) are lobed to change the power band of the engine. Valves may stay open longer, close quicker than the stock cam was designed for. This is why idle may sound “choppier" and run rough at idle.Can you over cam an engine? ›
"The very worst thing you can do is over-cam an engine," Consolo says. "Lift, duration, and lobe separation angle need to be matched to the true end purpose; getting any one of those wrong can over-cam the engine, which is worse than under-camming." That's from both a power and enjoyment perspective.How long do you break-in a camshaft for? ›
