Owner Reviews on Power Gains
Many Chevy 350 owners have shared their experiences with various modifications. Here are some insights into the power gains reported from popular mods:
Intake Manifold Upgrades
Upgrading the intake manifold is one of the most common mods. Owners report an increase in horsepower ranging from 15 to 25 HP, depending on the specific manifold chosen and the overall setup of the engine.
Performance Carburetors
Switching to a performance carburetor can lead to a noticeable increase in throttle response and overall power. Owners have reported gains of 10 to 20 HP, with improved fuel delivery contributing to better performance.

Cylinder Head Modifications
Cylinder head modifications, such as porting and polishing, can yield significant power increases, often between 30 to 50 HP. However, these mods can be costly and require skilled labor.
Camshaft Upgrades
Changing the camshaft is another way to boost power. Owners have reported gains of 20 to 40 HP, depending on the cam profile selected. This mod can also change the engine’s power band, making it more suitable for specific driving styles.
EFI Conversions
Converting to an Electronic Fuel Injection (EFI) system can improve fuel efficiency and power. Many owners report a smoother power delivery and gains of 15 to 25 HP, along with better drivability.
Cost-Effectiveness of Chevy 350 Mods
While power gains are a significant factor, the cost-effectiveness of modifications is equally important. Here’s a breakdown of costs associated with common mods and their perceived value:
