The A-body Mopar platform is a popular choice for car enthusiasts looking to upgrade their vehicles for performance. With the right modifications, handling 500 horsepower safely and cost-effectively is achievable. This article will explore various drivetrain upgrades that can help you reach that horsepower goal while maintaining reliability and affordability.
Understanding the A-Body Mopar Platform
The A-body Mopar platform includes models like the Dodge Dart, Plymouth Valiant, and others produced between the 1960s and 1970s. Known for their lightweight construction and compact design, these vehicles are ideal for performance upgrades. However, to handle increased horsepower, several key components must be upgraded.
Key Drivetrain Components for Upgrades
- Transmission
- Rear End
- Driveshaft
- Engine Mounts
Transmission Upgrades
The transmission is a crucial component when handling increased horsepower. Upgrading to a high-performance transmission ensures that power is effectively transferred to the wheels.
- Torque Flight 727: A popular choice for A-body Mopars, it can handle more power than the stock transmission.
- Overdrive Transmissions: Consider upgrading to a 500 or 518 transmission for better fuel efficiency and improved highway performance.
Rear End Upgrades
The rear end of your A-body Mopar must be able to handle the torque from a 500 hp engine. Upgrading to a stronger rear end will improve traction and durability.
- 8.75-inch Rear End: Known for its strength, this rear end is a common upgrade for those seeking higher horsepower.
- Ford 9-inch Rear End: Offers customization options and is known for its durability, making it a great choice for high-power applications.
Driveshaft Considerations
With increased power, the driveshaft must be upgraded to prevent failure. A stronger driveshaft will ensure that power is efficiently transmitted to the rear end.
- Aluminum Driveshaft: Lightweight and strong, an aluminum driveshaft can reduce rotational mass and improve performance.
- Steel Driveshaft: Offers durability and strength, making it suitable for high-torque applications.
Engine Mount Upgrades
To handle the increased torque from a high-powered engine, upgrading engine mounts is essential. This will help reduce engine movement and improve overall stability.
- Polyurethane Engine Mounts: These mounts provide better support and reduced flex compared to stock mounts.
- Solid Engine Mounts: For maximum stability, solid mounts eliminate any movement but may transmit more vibration to the chassis.
Cost-Effective Performance Upgrades
Achieving 500 hp doesn’t have to break the bank. There are several cost-effective upgrades that can help you reach your horsepower goals without sacrificing quality.
Budget-Friendly Engine Modifications
Modifying your engine can be one of the most impactful ways to increase horsepower. Here are some budget-friendly options:
- Intake Manifold Upgrade: Swapping out the factory intake for a performance manifold can improve airflow and increase power.
- Headers: Upgrading to headers allows for better exhaust flow, contributing to increased horsepower.
- Carburetor or EFI Tuning: Proper tuning can yield significant horsepower gains without major expenses.
Suspension and Tire Upgrades
Handling 500 hp also means upgrading your suspension and tires to ensure that the power can be effectively put to the ground.
- Upgraded Shocks and Struts: Improve handling and ride quality with high-performance shocks and struts.
- Performance Tires: Invest in tires that provide better grip to handle the increased power safely.
Safety Considerations
Safety should always be a priority when modifying your vehicle for performance. Here are some key safety upgrades to consider:
- Roll Cage: Installing a roll cage can provide added protection in case of an accident.
- Upgraded Brakes: Ensure that your braking system can handle the increased speed and power with performance brake components.
- Safety Harness: A 5-point harness can help keep you securely in place during high-performance driving.
Conclusion
Upgrading your A-body Mopar to handle 500 hp safely and cost-effectively is a rewarding endeavor. By focusing on key drivetrain components, making budget-friendly modifications, and prioritizing safety, you can enjoy the thrill of high-performance driving while keeping your vehicle reliable and enjoyable.
