The old Winston cup engines were only 358 CID and put out close to 800 HP normally aspirated. The easiest way to make that much power on the street, though, would be with lots of cubic inches, good cylinder heads, and lots of intercooled boost. The engine in Keith Turk's old Camaro is a 406 CI SBC that makes 1600 HP. It has a centrifugal supercharger that feeds through an intercooler. It's not cheap to make that much power. Even with a SBC! Wht out....
