How much hp does a chevy 302 small block have?

There's no single answer to how much horsepower a Chevy 302 small-block has. Chevrolet never actually produced a 302 cubic inch small block engine. The closest they got were some variations around that displacement, but the horsepower varied drastically depending on the year, model, and options. You'd need to specify the exact year and model of the vehicle to even begin to get an estimate.
