Ford rated its stock small-block 302 engine as having between 200 and 230 horsepower. The engine can be modified, however, to increase the horsepower to over 400.
By upgrading just the cylinder heads, headers and rockers, the Ford 302 can put out as much as 402 horsepower. Further temporary increases can be made using nitrous or other power-additives to fuel lines. The horsepower of this engine has gotten as high as 479 but that required upgrading nearly every aspect of the engine. Ford's 302 engine was made in 1969 and 1970 and was again released in the years 2012 to 2013.
