How much horse power can you get froma Chevy 350?

The horsepower you can get from a Chevy 350 small-block engine depends heavily on modifications. A completely stock, original 350 from a car might only produce around 150-200 horsepower. However, with modifications, you can significantly increase this.

Highly modified 350s can easily reach 400-500 horsepower, and with serious engine building (forged internals, forced induction like a turbocharger or supercharger, extensive porting and polishing, etc.), you could even push 600 horsepower or more. There's really no upper limit with enough money and effort.
