Big horsepower 318 builds

Most street guys want around 0.9-1.1 hp per cid for a built street performance engine so for a 365 would be 330-400 hp and peak hp rpm of 4500-5500 rpm ish. To me 1.1-1.3 hp per cid is a street strip engine. Above that depending on the person you start to get into more of a race engine.
