The engine was rebuilt, so since the rebuild, it has 6k miles. the engine is at my friends garage, and the body is still at the shop. It has a dual intake that came with it. I just looked, and it says SU on the side of it. He could of taken a SU off the dual intake, and put it on the single. It also has a crane cams fireball XR700 ignition box, looks to be never hooked up.
