Here's one of my projects. When I built it in the early 80's it had a 105 hp Rotax engine and a cage. The class died out and it sat for many years. Then I decided to make a "pit mule" out of it to move my restored 60's sprinter around. Now it has a Tecumseh 8 hp engine, Comet torque-converter clutch, and a mid 40's Dodge pickup 3-speed tranny.
It's stored away now....in the cube van you can see in the photos. I faked the Offy stacks and 4-into-1 header just for effect.
