by

The A-body Mopar cars, known for their lightweight construction and classic styling, have become a popular choice for drag racing enthusiasts. However, transforming these vehicles into drag strip-ready machines comes at a cost. This article explores the various expenses involved in upgrading an A-body Mopar for the drag strip, including power enhancements, necessary parts, and labor considerations.

Understanding the A-body Mopar

The A-body Mopar platform includes models like the Plymouth Barracuda and Dodge Dart. These cars are celebrated for their performance potential and can be modified to achieve impressive quarter-mile times. The first step in preparing an A-body for drag racing is understanding its capabilities and limitations.

Power Enhancements

To achieve optimal performance on the drag strip, significant power enhancements are often necessary. This section outlines the common modifications and their associated costs.

Engine Upgrades

Upgrading the engine is one of the most critical aspects of preparing an A-body Mopar for drag racing. Common modifications include:

  • Performance Camshaft: Upgrading to a high-performance camshaft can improve engine breathing and increase horsepower. Cost: $500 – $1,500.
  • Intake Manifold: Installing a high-flow intake manifold allows for better air-fuel mixture. Cost: $300 – $800.
  • Exhaust System: A performance exhaust system reduces back pressure and enhances sound. Cost: $400 – $1,200.
  • Carburetor: Upgrading to a larger carburetor can significantly boost performance. Cost: $300 – $700.
  • Forced Induction: Adding a supercharger or turbocharger can drastically increase horsepower. Cost: $2,000 – $8,000.

Transmission Modifications

The transmission plays a crucial role in delivering power to the wheels. Upgrading the transmission can enhance performance and durability:

  • Performance Torque Converter: A high-stall torque converter can improve acceleration. Cost: $300 – $800.
  • Transmission Rebuild: Rebuilding the transmission with performance parts ensures it can handle increased power. Cost: $1,000 – $2,500.
  • Shift Kit: Installing a shift kit can improve shift response and performance. Cost: $100 – $300.

Parts and Components

In addition to power enhancements, various parts and components are necessary to ensure the A-body Mopar is drag strip ready. Below is a breakdown of essential parts and their costs.

Suspension Upgrades

A well-tuned suspension is vital for maintaining traction and stability during a drag race:

  • Drag Racing Springs: Upgrading to drag racing springs can improve weight transfer. Cost: $200 – $600.
  • Adjustable Shocks: Installing adjustable shocks allows for tuning based on track conditions. Cost: $300 – $800.
  • Subframe Connectors: Adding subframe connectors increases chassis rigidity. Cost: $100 – $300.

Brake System Enhancements

Improving the braking system is essential for safety and performance:

  • Performance Brake Pads: Upgrading to high-performance pads improves stopping power. Cost: $100 – $300.
  • Slotted Rotors: Slotted rotors enhance heat dissipation and braking performance. Cost: $200 – $500.
  • Brake Lines: Installing stainless steel brake lines increases responsiveness. Cost: $100 – $200.

Tires and Wheels

Choosing the right tires and wheels can significantly impact performance on the drag strip:

  • Drag Radials: Investing in specialized drag radials improves traction. Cost: $400 – $1,200 for a set.
  • Lightweight Wheels: Lightweight wheels reduce unsprung weight and improve acceleration. Cost: $800 – $2,000 for a set.

Labor Costs

Labor costs can vary significantly depending on the complexity of the modifications and the shop’s hourly rate. Here are some considerations:

  • Mechanic Labor: Expect to pay between $75 – $150 per hour for skilled labor.
  • Installation of Performance Parts: Labor for installing performance parts can range from $500 – $2,000 depending on the scope of work.
  • Tuning: Professional tuning is crucial after major modifications and can cost $300 – $1,000.

Estimating Total Costs

When considering the total cost of making an A-body Mopar drag strip ready, it is essential to account for all aspects, including power enhancements, parts, and labor. Below is a rough estimate:

  • Power Enhancements: $5,000 – $20,000.
  • Parts and Components: $3,000 – $10,000.
  • Labor Costs: $1,000 – $5,000.

In total, the cost to prepare an A-body Mopar for the drag strip can range from approximately $9,000 to over $35,000, depending on the extent of modifications and quality of parts used.

Conclusion

Transforming an A-body Mopar into a drag strip-ready vehicle requires careful planning and investment. By understanding the costs associated with power enhancements, necessary parts, and labor, enthusiasts can make informed decisions to achieve their racing goals. Whether you’re a seasoned racer or a newcomer, the thrill of drag racing in an A-body Mopar is a rewarding experience.
