by

The AMC Javelin is a classic muscle car that has captured the hearts of enthusiasts for decades. If you’re looking to boost the performance of your Javelin, an Edelbrock intake and exhaust swap can provide significant horsepower gains. In this article, we will explore how to achieve over 50 horsepower with these modifications and maximize your AMC Javelin’s potential.

Understanding the AMC Javelin

The AMC Javelin was introduced in 1968 as a competitor in the pony car market. With its sleek design and powerful engine options, it quickly became a favorite among muscle car enthusiasts. The Javelin was available with various engines, including the 290, 343, and 390 cubic inch V8s, which provided a solid foundation for performance upgrades.

Benefits of Edelbrock Intake and Exhaust Swap

Upgrading to an Edelbrock intake manifold and exhaust system can lead to substantial performance improvements. Here are some key benefits:

  • Increased Airflow: Edelbrock components are designed to improve airflow, which can enhance engine efficiency.
  • Better Throttle Response: A new intake and exhaust system can provide quicker throttle response, making your Javelin more enjoyable to drive.
  • Weight Reduction: Edelbrock parts are often lighter than stock components, contributing to a better power-to-weight ratio.
  • Improved Sound: A new exhaust system can give your Javelin a more aggressive sound that enhances the driving experience.

Choosing the Right Edelbrock Components

When selecting Edelbrock components for your Javelin, consider the following options:

  • Edelbrock Performer RPM Intake Manifold: This manifold is designed for high-performance applications and can significantly increase horsepower and torque.
  • Edelbrock Headers: Upgrading to headers can improve exhaust flow and reduce back pressure, contributing to horsepower gains.
  • Edelbrock Exhaust System: A complete exhaust system designed for your Javelin can enhance sound and performance.

Installation Process

Installing an Edelbrock intake and exhaust system requires some mechanical knowledge and tools. Here’s a step-by-step guide to help you through the process:

Tools and Materials Needed

  • Socket set
  • Wrenches
  • Screwdrivers
  • Torque wrench
  • Gasket scraper
  • New gaskets
  • Shop towels

Step-by-Step Installation

  • Preparation: Begin by disconnecting the battery and removing any components obstructing access to the intake and exhaust.
  • Remove the Old Intake: Unscrew the bolts securing the old intake manifold and carefully lift it off.
  • Clean the Surface: Use a gasket scraper to clean the engine surface where the new intake will be installed.
  • Install the Edelbrock Intake: Place the new intake manifold onto the engine, ensuring proper alignment with the gaskets.
  • Tighten Bolts: Use a torque wrench to tighten the intake bolts to the manufacturer’s specifications.
  • Remove the Old Exhaust: Unscrew the bolts from the exhaust manifold and detach the old exhaust system.
  • Install the Edelbrock Headers: Position the new headers and secure them with bolts.
  • Attach the New Exhaust System: Follow the manufacturer’s instructions to attach the new exhaust system, ensuring a secure fit.
  • Reconnect Components: Reinstall any components removed during the process and reconnect the battery.
  • Test Drive: Start the engine and take your Javelin for a test drive to experience the improvements.
