As automotive enthusiasts, you understand that the heart and soul of your beloved Chevrolet Camaro SS is its engine. And the camshaft, often referred to as the ‘brain’ of the engine, plays an integral role in controlling the intake and exhaust valves for optimal engine performance. The art of swapping the stock camshaft for a performance variant can significantly enhance the power output, torque, and overall driving experience of your Camaro. However, the process can be technical and requires careful attention. But don’t worry, we will guide you on how to successfully install a performance camshaft in your Chevrolet Camaro SS.
Choosing the Right Performance Camshaft
Before delving into the installation process, it’s crucial to select the right camshaft for your engine. The camshaft controls the valve timing, lift, and duration of the valves. When you choose a performance cam, it’s essential to consider the specifications that will meet your specific driving needs.
Performance cams come in a variety of profiles that determine the engine’s power band – the RPM range where the engine produces the most power. If you’re an adrenaline junkie craving for high-speed thrills, go for a cam with a high lift and long duration. On the other hand, if you want more low-end torque for street cruising, a cam with a shorter duration and lower lift would be a better fit.
Preparation before Installation
Before you begin the installation process, gather all the necessary tools such as a torque wrench, thread locker, feeler gauge, engine oil and a camshaft installation handle. Ensure you also have a clean workspace with enough room to lay out all the parts. The next step involves preparing your Camaro’s engine.
Begin by disconnecting the battery and draining the engine oil. Remove the air intake assembly and disconnect the radiator hoses. You will need to remove the front of the engine, including the water pump, timing cover, balancer, and timing chain or belt. At each step, keep track of your bolts and their location for easy reinstallation. Remember, this is not a race, but a meticulous task that requires patience and accuracy.
Removing the Existing Camshaft
The removal of the existing camshaft in your Camaro’s engine is a careful task. To gain access to the camshaft, you’ll need to remove the rocker arms, pushrods, and lifters. It’s important to keep these in order as they need to go back into their original positions during reinstalling.
Next, remove the cam gear and timing chain. This will give you access to the camshaft. Slowly pull out the camshaft, making sure not to scratch or ding the cam bearings. Once the camshaft is out, clean the cam bearing journals thoroughly to remove any old oil or debris.
Installing the Performance Camshaft
Installing a performance camshaft entails a careful process. Start by applying a high-pressure lubricant on the bearing surfaces and lobes of the new performance cam. Follow this with engine oil on the distributor gear and the camshaft thrust surface.
Once the new cam is well lubricated, gently slide it into the cam bearings. Use caution to avoid damaging the bearings or hitting the pistons. Once the camshaft is in place, reinstall the timing chain or belt, ensuring the timing marks align correctly. Double-check the camshaft end play to ensure there’s no binding or excessive play.
Now, reinstall the lifters, pushrods, and rocker arms in their respective locations. Make sure you torque the bolts according to the manufacturer’s specifications. Don’t forget to apply thread locker where necessary to prevent loosening due to vibrations.
Fine-Tuning and Break-In
Once the camshaft installation is complete, follow up by reinstalling the front of the engine, including the water pump, timing cover, and balancer. Refill the engine with fresh oil and reconnect the battery.
Before starting your Camaro, prime the oil pump to ensure proper lubrication. This can be done by spinning the oil pump with a drill and priming tool while the distributor is out. Once primed, reinstall the distributor.
Turn on the engine and let it idle at a moderate RPM for about 30 minutes. This break-in period allows the camshaft and lifters to wear into each other and establish a good surface finish.
Remember, a successful performance camshaft installation is a blend of careful selection, meticulous installation, and thoughtful break-in. By following these steps, you can unlock the true potential of your Chevrolet Camaro SS and enjoy a thrilling driving experience.
Finishing Up and Post-Installation Tips
After the critical break-in period, it is time to finish up the process. Start by giving the car a thorough once-over to ensure everything is in place. Inspect the water pump, timing cover, and oil pan for any signs of leakage. Also, check the valve springs and rocker arms to ensure they are securely fastened and operating correctly.
Next, adjust your valve stem seals if necessary. Uneven or excess wear can lead to oil leakage or poor engine performance. Remember to always follow the manufacturer’s specifications when tightening or adjusting components.
Ensure every part that was removed, like the radiator hoses and air intake assembly, are reinstalled correctly. Finally, reconnect the battery and refill the oil to the proper level.
It is essential to remember that your Chevrolet Camaro SS may behave differently after installing the performance camshaft. It may have a rough idle due to the high lift and valve duration. This is a normal occurrence and a sign that your Camaro is now a high-performance machine.
Take your time to get used to the new powerband and torque curve. Also, regularly check your engine oil, as aggressive cam profiles can result in increased oil consumption.
Conclusion: Revel in Your Revamped Performance
You’ve followed the intricate process of a performance cam install, from choosing the right cam to the careful installation, and the all-important break-in period. You’ve worked with an array of parts from the timing chain to the valve springs, and even the water pump. With every bolt turned and every component inspected, you’ve unlocked a new level of performance from your Chevrolet Camaro SS.
Now, it’s time to hit the road and feel the power of your revamped Camaro. Whether it’s impressing on the race track or cruising down the street, your knowledge and hard work have paid off in an enhanced driving experience.
Remember, regular maintenance is crucial for the longevity of your new performance cam. Regularly check your oil levels and look out for any signs of wear or damage.
Installing a performance camshaft is a rewarding task that breathes new life into your vehicle. Revel in the satisfaction of not only the increased power and performance but also the knowledge that you’ve successfully completed a complex mechanical procedure. So buckle up, hit the road, and let your Chevrolet Camaro SS roar into life.
