Engine & Drivetrain Our Mustang has the "C" code 289 cubic inch engine that had 200 horsepower. Ours is restored and painted the correct Ford Blue as well as the valve covers and factory air cleaner. It has everything in the painted and detailed engine compartment looking like it just got off the assembly line, from the correct factory exhaust manifolds, power steering, to all the belts and hoses too. It is backed up by a 4-speed transmission and has a single exhaust system flowing out the back lower body panels.
