However, here's a *general* overview of the process. This is not a comprehensive guide and should not be considered a substitute for a proper workshop manual specific to your engine and camshaft kit:
1. Preparation:
* Gather tools: You'll need a variety of tools including engine stand (highly recommended), socket set, torque wrench, camshaft installation tool, valve spring compressor, timing chain/belt tools, degreaser, engine hoist (if not using an engine stand), and a clean workspace.
* Consult your camshaft kit instructions: Each camshaft kit comes with specific instructions and potentially unique tools or procedures. Follow those instructions religiously.
* Drain fluids: Drain the engine oil and coolant.
* Remove the engine: It's much easier to work on the engine outside the vehicle on an engine stand.
* Disassemble the top end: Remove the valve covers, rocker arms, pushrods, intake manifold, and heads. Take pictures and note the locations of parts for reassembly.
2. Camshaft Installation:
* Inspect the block: Carefully inspect the camshaft journals (the surfaces where the camshaft sits) for any damage.
* Install the camshaft bearings: These are typically installed in the block. Make sure they are properly seated.
* Install the camshaft: Using the appropriate camshaft installation tool (prevents damage), carefully install the camshaft into the block. Ensure it's properly aligned. Pay close attention to the timing marks (usually dots or notches) on the camshaft and the timing chain/belt gears.
* Install lifters: Install the lifters into the block. Some lifters require priming with oil before installation.
3. Timing Chain/Belt Installation:
* Install the timing chain or belt: This is crucial for proper engine timing. Again, carefully align the timing marks on the crankshaft, camshaft, and timing chain/belt components. The specific procedure varies depending on if you have a timing chain or belt.
* Install the timing cover: Once timing is confirmed, install the timing cover.
4. Reassembly:
* Install the pushrods: Install the pushrods, ensuring they're the correct length.
* Install the rocker arms: Install the rocker arms, making sure they're properly adjusted.
* Install the valve covers: Install the valve covers and tighten appropriately.
* Reinstall the heads: Torque head bolts to the manufacturer's specifications.
* Reassemble the rest of the engine: Reinstall the intake manifold, distributor (if applicable), and other components.
* Refill fluids: Refill the engine oil and coolant.
5. Final steps:
* Check for leaks: Once the engine is reassembled, carefully check for any leaks.
* Initial start-up: Start the engine and let it run for a few minutes to check for any unusual noises or problems.
* Break-in period: Follow the camshaft manufacturer's break-in procedure, which typically involves running the engine at different RPMs for a specified amount of time.
Crucial Considerations:
* Timing: Accurate timing is absolutely critical. Incorrect timing can lead to engine damage.
* Torque specifications: Use the correct torque specifications for all bolts and nuts. Over-tightening can damage components.
* Cleanliness: Maintain a clean workspace and handle all parts carefully to prevent damage or contamination.
* Professional help: If you're not confident in any step of this process, seek the help of a qualified engine mechanic.
This is a simplified outline. A detailed procedure will be found in a reliable repair manual specific to your 350 Chevy engine and the specific camshaft you are installing. Again, this is a complex process and attempting it without experience could result in significant engine damage. Consult a professional if you lack the necessary experience.
