The Pontiac GTO is a piece of automotive history: it arguably invented the "muscle car" as we know it, and it remains a highly desirable classic to this day. This particular example boasts a Tri-Power V8 engine and a 5-speed manual transmission swap. Power comes from a 389-cubic-inch Tri-Power V8, rated at about 330 horsepower and 430 lb-ft of torque. Output is sent to the rear wheels via a 5-speed manual transmission.
