Chevrolet’s Enduring 350 Power As we’ve mentioned, the Chevy 350 small block V8 engine is a powerful modular engine for the car project owner. You can expect it to range from 4.3L versions to as high as 5.7L (and even 6.6L) in the more modern versions of the engine. While it may vary on the year, make, and model, you can expect horsepower (HP) to range from 145 to above 370. The amount of torque generated (around 380 pounds per foot) makes this a great option for small trucks and towing vehicles. Despite relatively lower fuel economy, users of the Chevrolet 350 small block V8 swear by its performance when using good quality fuels. Even after 52 years since its first inception, the 350 remains a powerful engine when placed in comparison to its contemporaries.
