Top Cheap Mods for Chevy 454
Here are some of the best modifications you can make to your Chevy 454, all within the $200-$400 range, that can help you achieve those desired horsepower gains.
1. Cold Air Intake
A cold air intake system can significantly improve airflow to your engine, leading to better combustion and increased horsepower. By replacing the factory air intake with a performance model, you can gain anywhere from 10 to 20 horsepower.

Upgrading your exhaust system can reduce back pressure and improve exhaust flow. A performance cat-back exhaust system can enhance sound and performance, potentially adding 10 to 15 horsepower.
3. High-Performance Spark Plugs
Installing high-performance spark plugs can improve ignition efficiency and engine performance. This simple upgrade can lead to better throttle response and a slight increase in horsepower.
4. Re-gearing the Differential
Changing the gear ratio in your differential can enhance acceleration and overall performance. While this mod doesn’t directly increase horsepower, it can make your vehicle feel more powerful and responsive.
5. ECU Tune
A performance ECU tune can optimize your engine’s fuel and timing settings for better performance. Many tuners can provide a significant horsepower increase for a relatively low cost.
