How To Get 500 Horsepower Out Of A 350

How to Get 500 Horsepower Out of a 350 Small Block Chevy

The venerable 350 small-block Chevy engine: a legend in the automotive world, known for its reliability, affordability, and incredible potential for modification. Many enthusiasts dream of unleashing the beast within, pushing this iconic engine beyond its factory limits. So, how do you get a whopping 500 horsepower out of a 350? It’s a significant undertaking, but absolutely achievable with the right approach. This guide will break down the key components and strategies.

Key Components for 500 Horsepower

Reaching 500 horsepower from a 350 isn’t about one single modification; it's about a synergistic combination of upgrades working together. Here are the crucial elements:

1. Internal Engine Upgrades: The Foundation of Power

• Forged Internal Components: Stock internals won’t withstand the stresses of a 500-horsepower engine. You'll need forged pistons, connecting rods, and a crankshaft capable of handling the increased power and pressure.
• Increased Displacement: Consider a stroker kit to increase the engine's displacement. This will significantly boost torque and horsepower. A 383 stroker kit is a popular choice.
• High-Performance Cylinder Heads: These heads offer larger valves, improved flow, and optimized combustion chambers for maximum power. Look for options with high flow rates and good chamber design.
• Aggressive Cam Profile: A performance camshaft with a higher lift and duration is crucial for increasing airflow and maximizing power output. Carefully select a cam profile that matches your engine's other modifications.

2. Induction System: Breathing Easy

• High-Performance Intake Manifold: The intake manifold is responsible for delivering air to the engine. A high-performance manifold optimized for your specific setup will dramatically improve airflow.
• High-Flow Air Filter: Ensure unrestricted airflow with a large, high-flow air filter.
• Throttle Body: A larger throttle body will improve airflow further, especially at higher RPMs.

3. Fuel System: Feeding the Beast

• High-Performance Fuel Pump: A high-volume fuel pump capable of delivering the necessary fuel to support 500 horsepower is essential.
• High-Flow Fuel Injectors: These injectors will deliver the precise fuel mixture required for optimal combustion.

4. Exhaust System: Exhausting the Power

• Headers: Long-tube headers significantly improve exhaust flow, increasing power and torque.
• Performance Exhaust System: A free-flowing exhaust system will remove exhaust gases efficiently, maximizing power gains.

5. Ignition System: Precise and Powerful

• High-Performance Ignition System: A reliable and powerful ignition system, including a performance coil and wires, is vital for consistent, high-energy sparks.

The Tuning Process: Dialing it In

Once all the parts are installed, professional tuning is critical. A dyno tune will ensure the engine is properly calibrated for optimal performance, safety, and reliability. This involves adjusting the fuel mixture, ignition timing, and other parameters to extract the maximum horsepower while preventing engine damage.

Considerations Beyond Horsepower

Remember that building a high-horsepower engine requires expertise. Proper installation and precise tuning are essential to prevent damage and ensure reliability. Consider consulting with experienced engine builders for assistance. Building a 500-horsepower 350 is a rewarding project but demands attention to detail and a commitment to quality parts. Enjoy the process and the impressive power!
