Big Block Engine Upgrades: Tips and Tricks for More Power

The allure of a big block engine lies in its raw power and torque. These engines are the heart of classic muscle cars, trucks, and other vehicles where performance is king. However, even the most potent big blocks can benefit from strategic upgrades. In this blog post, we'll delve into tips and tricks for upgrading your big block engine to achieve even more power.

Intake Manifold Upgrades

One of the first upgrades you should consider for your big block engine is the intake manifold. This can have a significant impact on airflow, fuel distribution, and ultimately, performance. Aftermarket intake manifolds are designed to offer superior air-fuel mixing, which can enhance horsepower and torque.

Camshaft Replacement

A camshaft upgrade can drastically improve your engine's performance by optimizing valve timing, lift, and duration. When choosing a camshaft, consider your vehicle's primary use—whether it's for daily driving, towing, or racing—to ensure you get the optimal performance gains.

Exhaust System Modifications

Upgrading the exhaust system can improve horsepower by reducing back pressure and improving exhaust gas flow. Long-tube headers paired with a performance exhaust system can make a noticeable difference in how your big block engine performs.

Fuel Injection Systems

While many big block engines come with carburetors, upgrading to a modern fuel injection system can offer improved fuel economy, better throttle response, and increased horsepower. EFI systems are more efficient and provide a more precise air-fuel mixture than carburetors, enhancing overall performance.

Big Block: The Epitome of Raw Power

The term "Big Block" is synonymous with high-performance, versatility, and, most importantly, power. These engines are designed to produce massive amounts of torque and horsepower, making them the ideal choice for muscle cars, trucks, and racing applications. However, with the right upgrades, such as intake manifolds, camshafts, and fuel systems, you can push your big block engine to even greater heights. Whether you're on the drag strip or simply want to enjoy a more powerful ride, these upgrades offer the next level of performance.

Turbocharging and Supercharging

Adding a turbocharger or supercharger to your big block engine can exponentially increase horsepower. While these upgrades require a significant investment, the power gains are unmatched. Turbochargers use exhaust gases to spin a turbine, compressing air and forcing it into the engine for a significant horsepower boost. Superchargers, on the other hand, are mechanically driven by the engine's crankshaft and offer a more immediate power increase.

Cooling Systems

Don't overlook the importance of an efficient cooling system when upgrading your big block engine. High-performance engines generate a lot of heat, and an upgraded cooling system ensures that your engine stays within optimal operating temperatures, prolonging its lifespan and ensuring consistent performance.

LS Engine: A Modern Alternative?

While big block engines are iconic for their brute power and torque, it's worth mentioning that modern engine options like the LS engine also offer exceptional performance and efficiency. Known for its compact size, lighter weight, and fuel efficiency, the LS engine has become a popular choice for modern performance builds. However, when it comes to raw, untamed power, many still prefer the roaring intensity of a big block engine. In the end, the best engine for your project depends on your specific needs and performance goals.


Upgrading a big block engine is a rewarding venture for those looking to maximize performance. From simple tweaks like upgrading the intake manifold and exhaust system to more significant changes like adding a turbocharger, there's a plethora of options to explore. While modern options like the LS engine offer their own set of advantages, the big block remains a symbol of raw power and performance. Whatever your project may be, these tips and tricks should help you squeeze even more power out of your big block engine.
