C4 Corvette Power Mods: Installing a 4-point Displacement and Camshaft for 350 Hp

The C4 Corvette is a classic American sports car that has captured the hearts of many enthusiasts. One of the most sought-after modifications for increasing performance is the installation of a 4-point displacement and camshaft. This article will guide you through the process of achieving 350 horsepower through these modifications.

Understanding the Basics

Before diving into the installation process, it’s essential to understand what a 4-point displacement and camshaft modification entails. The 4-point displacement refers to increasing the engine’s cubic inches, while the camshaft controls the timing and duration of the engine’s intake and exhaust valves.

Benefits of Modifying Your C4 Corvette

Modifying your C4 Corvette with a 4-point displacement and camshaft can lead to significant performance improvements. Here are some of the key benefits:

  • Increased horsepower and torque
  • Improved throttle response
  • Enhanced engine sound
  • Better overall driving experience

Parts Required for Installation

Gathering the right parts is crucial for a successful installation. Below is a list of components you will need:

  • 4-point displacement engine kit
  • Performance camshaft
  • New gaskets and seals
  • Timing chain and gears
  • Engine oil
  • Coolant
  • Tools (wrenches, sockets, etc.)

Step-by-Step Installation Process

Step 1: Preparation

Before starting the installation, ensure you have a clean workspace. Disconnect the battery and drain the engine oil and coolant to prevent spills during the process.

Step 2: Remove the Old Camshaft

To access the camshaft, you will need to remove the intake manifold and any other components blocking access. Once exposed, carefully remove the old camshaft by following these steps:

  • Remove the timing cover
  • Take out the timing chain
  • Unbolt the camshaft and slide it out

Step 3: Install the New Camshaft

With the old camshaft removed, install the new performance camshaft. Make sure to align it correctly and secure it in place. Reinstall the timing chain and cover as per the manufacturer’s instructions.

Step 4: Upgrade the Engine Displacement

Next, you will need to increase the engine displacement. This typically involves replacing the pistons and possibly the crankshaft. Follow these steps:

  • Remove the engine from the vehicle
  • Take off the oil pan and cylinder heads
  • Replace the pistons with larger ones
  • Reassemble the engine components

Step 5: Reassemble and Test

Once all modifications are complete, reassemble the engine and reinstall it into the Corvette. Reconnect all components, fill the engine with oil and coolant, and reconnect the battery. Start the engine and listen for any unusual noises.

Tuning Your C4 Corvette

After installation, tuning is essential to ensure optimal performance. Consider the following:

  • Adjust the fuel-air mixture
  • Set the ignition timing
  • Use a dynamometer to measure horsepower and torque

Conclusion

Installing a 4-point displacement and camshaft in your C4 Corvette can significantly enhance its performance, achieving an impressive 350 horsepower. With the right tools and parts, along with careful installation and tuning, you can enjoy a thrilling driving experience like never before.
