Are you a fan of hot rods, muscle cars, and all things automotive? If so, then you know the importance of a good camshaft in your engine build.
But with so many options out there, how do you know which one is right for your ride?
That’s why in this blog we’re going to be talking about one key element of cam selection: the identification numbers.
What is comp cam identification numbers location?
Comp cam identification numbers are typically located on the end of the camshaft, near the distributor gear. This location is also known as the “front” of the camshaft.
To identify a Comp camshaft, you will need to look for a series of letters and numbers etched or stamped onto the end of the camshaft.
These numbers will usually be a combination of letters and numbers, such as “XE274H-10” or “CL12-246-3.”
The numbers and letters used in Comp cam identification codes can provide a lot of information about the camshaft.
For example, the “XE” in the code “XE274H-10” stands for “Xtreme Energy,” which is a series of camshafts that Comp Cams produces.
The “274” refers to the duration of the camshaft (how long the valves stay open), while the “H” indicates that it has a hydraulic lifter design.
Meanwhile, the “CL” in the code “CL12-246-3” stands for “Cam and Lifter,” which is another series of camshafts produced by Comp Cams.
The “12” refers to the engine type (in this case, a Chevy small-block), while the “246” refers to the duration of the camshaft. Finally, the “3” indicates the number of lobes on the camshaft.
It’s worth noting that not all Comp Cams will have identification numbers etched onto the end of the camshaft.
Some camshafts will have stickers or tags attached to the packaging or paperwork that provide the identification information.
Where to Look for Comp Cam Identification Numbers?
Comp Cam identification numbers can usually be found in a few different places. Here are some key places to look for Comp Cam identification numbers:
1. Camshaft box or packaging:
The Comp Cam identification number should be clearly marked on the box or packaging that the camshaft came in.
This is usually the easiest place to find the number and should be the first place to look.
2. Camshaft itself:
The Comp Cam identification number may also be stamped directly onto the camshaft.
This can usually be found near the distributor gear or on the end of the camshaft.
3. Camshaft specification card:
Comp Cams often come with a specification card that lists all the important details about the camshaft, including the identification number.
If you have this card, the identification number should be easy to find.
4. Comp Cams website:
If you’re having trouble finding the identification number or want to double-check your information, the Comp Cams website is a great resource.
You can search for your camshaft by engine type or part number, and the website will provide all the relevant information.
5. Manufacturer’s catalog:
If you have an older camshaft or don’t have access to the original packaging, you may be able to find the identification number in the manufacturer’s catalog.
This may require some research, but it can be a helpful resource if you’re having trouble finding the number elsewhere.
Common Issues When Identifying Comp Cam Identification Numbers
When it comes to identifying Comp Cam identification numbers, there are a number of common issues that people may encounter.
These issues can make the process of identifying a Comp Cam more difficult, so it’s important to be aware of them. Here are some of the most common issues:
1. Incomplete or incorrect information:
One common issue when identifying Comp Cam identification numbers is the presence of incomplete or incorrect information.
Sometimes, the information provided about a Comp Cam is not comprehensive or accurate enough to identify the camshaft correctly.
This can happen when essential details like specifications or product codes are missing.
Without complete and accurate information, it becomes challenging to match the camshaft to a specific product.
2. Confusion with other brands:
Comp Cams is not the only manufacturer of camshafts, and it’s possible to mistake camshafts from other brands for Comp Cams.
This confusion can occur if the markings on the camshaft are unclear or if the person trying to identify it is not familiar with the different brands and their respective identification systems.
It’s important to pay attention to the specific markings and features that distinguish Comp Cams from other brands.
3. Different versions of the same camshaft:
Comp Cams often releases different versions of the same camshaft model, each with its own unique specifications and performance characteristics.
This means that two camshafts with the same identification number may not necessarily be identical.
The different versions may vary in terms of lift, duration, or other factors that affect engine performance.
When identifying a Comp Cam, it’s crucial to consider the specific version or variant of the camshaft to ensure an accurate match.
4. Camshaft modifications:
Another common issue when identifying Comp Cam identification numbers is the presence of camshaft modifications.
Sometimes, people modify their camshafts by grinding or altering the lobes to achieve specific performance goals.
These modifications can change the camshaft’s characteristics and make it challenging to identify.
The markings on the lobes may no longer match the original specifications, making it necessary to assess the camshaft’s physical features and compare them to known references.
5. Limited availability of information:
In some cases, information about older or discontinued Comp Cams may be limited or unavailable.
This can be particularly challenging when trying to identify these camshafts, especially if there are no markings or other identifying features on the camshaft itself.
Limited availability of information can make it difficult to match the camshaft to its specific model or variant.
In such situations, it may be helpful to consult with experienced professionals or refer to resources that specialize in vintage or discontinued camshafts.
How does the comp cam identification number determine the specs of the camshaft?
Here’s a breakdown of how the Comp Cam identification number determines the specs of the camshaft:
The first two digits of the Comp Cam identification number indicate the lift of the camshaft. For example, if the identification number is 12-246-3, the lift is 0.5 inches.
The second set of numbers in the identification number tells you the camshaft’s duration.
This refers to how long the valves stay open during the engine cycle. For instance, if the number is 12-246-3, the duration is 246 degrees.
3. Lobe separation angle:
The final number in the identification number represents the lobe separation angle.
This is the angle between the intake and exhaust lobes on the camshaft.
It plays a vital role in determining the engine’s performance. If the number is 12-246-3, the lobe separation angle is 110 degrees.
In addition to these three critical specs, the Comp Cam identification number can also tell you about other features of the camshaft, such as the type of camshaft, the valve timing, and the recommended valve springs.
Why it’s important to have the correct identification number?
Having the correct identification number when ordering or installing a Comp Cam is essential for several reasons. Here are some important points to consider:
1. Ensure proper fitment:
Comp Cams are designed to work with specific engines and vehicles, and each camshaft has a unique identification number.
By using the correct identification number, you can ensure that the camshaft you order or install will fit properly in your engine, allowing it to function correctly.
2. Achieve desired performance:
Different camshafts have varying profiles and lift characteristics that can significantly affect engine performance.
Using the correct identification number will help you choose the camshaft that best suits your performance goals, ensuring that you get the desired power and torque gains.
3. Avoid damage to engine components:
Installing the wrong camshaft can cause serious damage to your engine, leading to costly repairs.
For example, if the camshaft has too much lift, it can cause the valves to hit the pistons, leading to catastrophic engine failure.
Using the correct identification number will ensure that you choose a camshaft that is compatible with your engine and will not cause any damage.
4. Warranty and support:
Comp Cams offer warranties on their products, but they require the correct identification number to be used during the ordering and installation process.
Using the wrong camshaft can void the warranty and leave you with no support if something goes wrong.
By using the correct identification number, you can ensure that you are covered by the manufacturer’s warranty.
