Many Optional Extras are available for a custom-build

When thinking about performance upgrades, you might want to consider the optional extras such as

• AFR 260 cylinder heads. These can help improve engine power.
• CNC Ported New LS3 Heads
• A Fast Manifold paired with a larger throttle body can also make a big difference in performance. These components work together to improve airflow, which is crucial for increasing horsepower.
• The AFR 260 cylinder heads are designed to optimize combustion efficiency. They feature larger intake and exhaust ports, allowing for better airflow into and out of the engine. This improvement can lead to a noticeable increase in power output.
• A larger throttle body lets more air enter the engine. Together, these upgrades can elevate the engine’s power to around 523 kilowatts (700 horsepower).
• You should also install a high-quality DPE Manta Pro performance exhaust system to get the most out of these upgrades.
• Additionally, consider adding an Over The Radiator (OTR) intake.
• A performance exhaust reduces back pressure, allowing exhaust gases to exit the engine more efficiently. This combination of upgrades boosts power and improves throttle response and overall engine performance.
• Performance Design Carbon XS Manifold and Granatelli 103mm Throttle body. Gains of approx 15rwkw and 25 Nm are possible. $3400
