Understanding Camshaft Specifications: Lift, Duration, and Lobe Separation Angle
Ever wondered why some LS engines sound like they’re about to shake the ground, while others purr like kittens? A big part of that sound, and more importantly, the performance, comes down to the camshaft specifications. We’re talking about lift, duration, and Lobe Separation Angle (LSA). These aren’t just fancy terms; they directly impact how your engine breathes and ultimately, how much power it makes. Think of it like this: lift determines how far the valve opens, duration determines how long it stays open, and LSA determines when those valves open and close in relation to each other.
Imagine you’re watering a plant. Lift is like opening the faucet wider – more water flows quickly. Duration is like how long you leave the faucet open – the longer it’s open, the more water the plant gets. LSA is like timing the watering – do you water it early in the morning or late in the evening? The right combination of these factors is crucial for a healthy, thriving plant (or in this case, a powerful LS engine!).
Choosing the wrong specs can have drastic consequences. Too much lift without the proper valve springs, and you risk valve float or even valve-to-piston contact. Too much duration for your application, and you’ll end up with a lumpy idle and poor low-end torque. And an LSA that doesn’t match your setup can lead to a narrow powerband and reduced overall performance.
So, before you dive into buying a cam, take the time to understand these core specifications. Research what works well with your engine’s displacement, compression ratio, and intended use. Chat with experienced LS enthusiasts and tuners to get their insights. A little knowledge goes a long way in ensuring you choose the right camshaft for your needs and achieve the performance goals you’re after.
Installation Tips and Tricks for LS Cams
Installing an LS cam can seem intimidating, but with the right preparation and a little know-how, it’s a manageable project for the experienced DIYer. Before you even crack open the engine, make sure you have all the necessary tools. A quality balancer installer/remover, a torque wrench, and the correct sockets are essential. Don’t skimp on tools; using the wrong ones can lead to stripped bolts and unnecessary headaches.
One crucial step is properly lubricating the new camshaft and lifters before installation. Use a high-quality assembly lube specifically designed for camshafts. This protects the cam lobes and lifter faces during the crucial break-in period. Think of it like applying sunscreen before a day at the beach – it’s vital to prevent damage.
Pay close attention to the timing marks when installing the camshaft and timing chain. Misaligning the timing can throw off the engine’s entire firing sequence, leading to poor performance or even engine damage. Double-check and triple-check your work to ensure everything is lined up correctly. It’s like making sure you have the right ingredients and measurements before baking a cake – accuracy is key.
Finally, the break-in period is critical for a new camshaft. Follow the manufacturer’s recommendations closely. Typically, this involves running the engine at a slightly elevated RPM for a specific amount of time to properly seat the lifters and allow the camshaft lobes to wear in smoothly. Neglecting this step can shorten the lifespan of your camshaft and lead to premature failure.
Matching Your Cam to Your Driving Style and Application
The best LS cam for you isn’t necessarily the one with the highest horsepower numbers. It’s the one that best suits your driving style and the intended use of your vehicle. Are you building a weekend warrior that spends most of its time at the drag strip, or a daily driver that needs to be reliable and fuel-efficient? The answer will significantly influence your cam selection.
Consider a street-driven car. A cam with too much duration might sound impressive at idle, but it can make the car difficult to drive in stop-and-go traffic. You’ll likely experience a loss of low-end torque, making it sluggish off the line. In this scenario, a smaller cam with a wider LSA would be a better choice, providing a broader powerband and better drivability.
On the other hand, if you’re building a dedicated race car, you’ll likely prioritize top-end horsepower over low-end torque. A larger cam with a tighter LSA could be ideal, allowing the engine to breathe better at high RPMs. However, be prepared for a more aggressive idle and potentially reduced fuel economy. It’s like choosing between a comfortable sedan for commuting versus a nimble sports car for track days – each is designed for a specific purpose.
Ultimately, choosing the right cam is about finding the right balance between power, drivability, and reliability. Talk to experienced builders or tuners who can help you assess your needs and recommend a camshaft that aligns with your goals. Don’t just chase the biggest numbers; focus on creating a well-rounded engine that performs optimally in your specific application.
Troubleshooting Common LS Cam Issues
Even with careful installation and the right cam selection, you might encounter some issues after installing an LS cam. Understanding these common problems and how to troubleshoot them can save you time, money, and frustration. One frequent issue is a noisy valvetrain. This can be caused by improper lifter preload, incorrect pushrod length, or even worn valve springs.
If you notice a ticking or clattering sound coming from the top of the engine, start by checking the lifter preload. This is the amount of travel the lifter plunger has after being installed. Too little preload can cause the lifter to rattle, while too much can prevent the valve from fully closing. It’s like adjusting the tension on a guitar string – too loose, and it buzzes; too tight, and it might break.
Another common problem is a rough idle or poor performance. This can be caused by a vacuum leak, improper timing, or even a faulty Mass Air Flow (MAF) sensor. Use a smoke machine or carb cleaner to check for vacuum leaks around the intake manifold and throttle body.
Don’t overlook the importance of a proper tune after installing a new camshaft. The engine’s computer needs to be recalibrated to account for the changes in airflow and fuel requirements. A professional tuner can optimize the engine’s performance and ensure it’s running safely. It’s like updating your phone’s software after installing a new app – it ensures everything works together seamlessly. If you face an issue, consulting with an experienced LS mechanic or tuner is always the best course of action.

This guide is designed to be your friendly co-pilot, helping you navigate the world of LS cams and choose the best ls cams for your specific needs and goals. We’ll break down the key factors to consider, so you can make an informed decision and unleash the true potential of your engine. Let’s dive in!
Intended Use and Driving Style
First things first, think long and hard about how you actually use your car. Are you building a weekend warrior for the drag strip, a comfortable street cruiser, or a combination of both? This is probably the most important question to ask yourself! A camshaft designed for all-out racing will likely be miserable to drive on the street, with a rough idle, poor low-end torque, and the need for high RPMs to make power. On the other hand, a mild street cam won’t cut it if you’re chasing every tenth of a second on the track.
Consider your driving habits too. Do you prefer instant throttle response and strong low-end pull, or are you more interested in top-end horsepower and the thrill of revving the engine to its limit? Be honest with yourself! There’s no point in choosing a cam that looks great on paper if it doesn’t match your driving style. The best ls cams are the ones that complement how you like to drive, allowing you to enjoy your car to its fullest potential. This honest assessment will help you narrow down your choices and avoid ending up with a cam that leaves you disappointed.
Camshaft Specs: Understanding the Jargon
Alright, let’s talk numbers! Camshaft specs can seem like a foreign language, but understanding them is crucial for choosing the right cam. Duration, lift, lobe separation angle (LSA), and overlap are the key parameters to pay attention to. Don’t worry, we’ll break them down! Duration refers to how long the valves are held open, lift is how far the valves open, LSA is the angle between the intake and exhaust lobes, and overlap is the period when both intake and exhaust valves are open simultaneously.
These specs all work together to influence the engine’s performance characteristics. Generally speaking, longer duration and higher lift will increase horsepower at higher RPMs, but can sacrifice low-end torque and idle quality. LSA affects the engine’s power band and idle smoothness. A tighter LSA (smaller angle) typically results in a narrower power band with more overlap and a choppier idle, while a wider LSA provides a broader power band and a smoother idle. It’s a delicate balancing act! Take the time to research these specifications and how they affect performance – knowledge is power! Remember, the best ls cams are the ones with specifications that match your intended usage and desired power curve.
Matching Components: The Supporting Cast
A camshaft doesn’t work in isolation! It’s part of a complex system, and you need to make sure all the other components are up to the task. This includes things like valve springs, pushrods, rocker arms, and even the intake manifold and exhaust system. Using the wrong components can lead to poor performance, valve float, or even engine damage. It’s like trying to run a marathon with the wrong shoes – you’re just setting yourself up for pain and failure!
Valve springs are particularly important. A more aggressive cam will require stronger valve springs to prevent valve float at high RPMs. Pushrods need to be the correct length and strong enough to handle the increased stresses. Rocker arms should be chosen to match the cam’s lift and provide the desired ratio. The intake manifold and exhaust system should be able to flow enough air to support the increased airflow provided by the cam. Think of your engine as a team, and the best ls cams as the star player. You need to ensure the rest of the team is ready to support that star player’s performance or you are going to be disappointed!
Tuning Requirements: Dialing It In
Once you’ve installed your new cam, you’ll need to get the engine tuned properly. A camshaft change alters the engine’s airflow and fuel requirements, so the factory tune will no longer be optimal. Without a proper tune, you’ll likely experience poor performance, rough idle, and even potential engine damage. It’s like buying a high-end stereo system and then plugging it into a potato – you’re not going to get the sound quality you’re expecting!
Tuning can be done with a handheld tuner, a dyno tune, or a custom tune from a professional tuner. A handheld tuner offers some adjustability, but a dyno tune or custom tune will provide the best results. A dyno tune involves running the engine on a dynamometer while the tuner adjusts the fuel and spark maps to optimize performance. A custom tune is tailored to your specific engine and modifications, taking into account factors like altitude, climate, and driving style. Budget for tuning when planning your cam swap, as it’s an essential step for maximizing the benefits of your new cam and ensuring long-term reliability. The best ls cams need the best tune to truly shine.
Idle Quality: The Sound of Performance
Let’s face it, a lot of us love the sound of a choppy idle! It’s a sure sign that something serious is going on under the hood. However, a very aggressive cam can result in an idle that’s so rough it’s unpleasant to live with on a daily basis. The engine might buck and shake, stall frequently, and generally make the car difficult to drive smoothly. It’s like having a wild animal trapped under the hood – exciting at first, but tiring after a while!
Consider how much you value idle quality. If you’re building a dedicated race car, you might be willing to sacrifice idle smoothness for maximum horsepower. But if you’re driving your car on the street, you’ll want a cam that offers a good balance between performance and drivability. Fortunately, modern camshaft designs and tuning techniques can often achieve surprisingly good idle quality even with relatively aggressive cams. Do your research and listen to sound clips of different cams to get an idea of what to expect. The best ls cams offer the right balance of performance and idle quality for your personal preferences.
Budget: How Much Are You Willing to Spend?
Let’s talk money! Camshafts themselves vary widely in price, depending on the brand, material, and design. However, the cost of the camshaft is just the beginning. You’ll also need to factor in the cost of other components, such as valve springs, pushrods, rocker arms, gaskets, and fluids. And of course, you’ll need to pay for installation and tuning. The total cost of a cam swap can easily add up to several thousand dollars.
Don’t be tempted to cut corners on quality. A cheap camshaft might seem like a good deal at first, but it could end up costing you more in the long run if it fails prematurely or causes damage to other engine components. It’s better to invest in a reputable brand and quality components that will provide reliable performance for years to come. Consider setting a budget and sticking to it as closely as possible. Research different options and compare prices before making a decision. The best ls cams may not be the cheapest, but they offer the best value for your money in terms of performance, reliability, and longevity.
