Upgrading your classic Chevy 283 with a Comp Cams camshaft can significantly enhance performance and give your engine a more aggressive sound. This guide will walk you through the step-by-step process of installing a Comp Cams camshaft, ensuring you achieve the best results for your classic car.
Tools and Materials Needed
- Comp Cams camshaft
- Socket set
- Torque wrench
- Engine oil
- Camshaft lubricant
- Timing chain and gears (if necessary)
- Gasket set
- Screwdrivers
- Rags and cleaning supplies
Preparation
Before starting the installation, ensure you have a clean workspace and all necessary tools at hand. Disconnect the battery and remove any components that may obstruct access to the engine, such as the air cleaner, valve covers, and timing cover.
Drain Engine Oil
To prevent any oil spillage during the installation, drain the engine oil. This will also allow you to replace the oil with fresh oil after the installation is complete.
Removing the Old Camshaft
With the engine prepared, you can now proceed to remove the old camshaft. Start by removing the timing chain and gears if they are in the way. Make sure to mark the position of the timing chain to ensure proper reinstallation.
Next, remove the lifters and pushrods. Keep them organized so you can reinstall them in the same order. Remove the camshaft retaining plate and take out the old camshaft carefully.
Installing the Comp Cams Camshaft
Before installing the new camshaft, apply camshaft lubricant to the lobes and journals to ensure proper lubrication during initial startup. Carefully slide the new camshaft into place, making sure it aligns with the timing chain and gears.
Reinstalling Lifters and Pushrods
Once the camshaft is in place, reinstall the lifters and pushrods. Ensure that each lifter is seated properly in its corresponding bore. This is crucial for the engine’s performance and longevity.
Reassembly
With the camshaft and lifters installed, it’s time to reassemble the engine. Reinstall the camshaft retaining plate and torque it to the manufacturer’s specifications. Replace the timing chain and gears, ensuring they are aligned correctly.
Next, reinstall the valve covers and any other components that were removed during the process. Make sure to replace any gaskets that may have been disturbed to prevent oil leaks.
Final Steps
Before starting the engine, refill it with fresh engine oil. Make sure to prime the oil system by cranking the engine without starting it. This will help circulate oil throughout the engine and lubricate the new camshaft.
Starting the Engine
After priming the oil system, reconnect the battery and start the engine. Allow it to idle for a few minutes while monitoring for any unusual sounds or leaks. It is normal for the engine to run a bit rough initially as the new camshaft breaks in.
Post-Installation Checks
After the engine has run for a short period, check the oil level and top off if necessary. Also, inspect for any leaks around the valve covers and timing cover. It’s essential to ensure everything is functioning correctly before taking your classic Chevy 283 for a drive.
Conclusion
Installing a Comp Cams camshaft in your classic Chevy 283 can significantly enhance your vehicle’s performance and driving experience. By following these steps carefully, you can ensure a successful installation and enjoy the benefits of your upgrade for years to come.
