This is a complete assembly build on the Atlas 4200 engine that we are going to be the world's fastest 4200 in a door car. This engine has been a round for some time, it was first seen at the 2005 Hot Rod Drag Week event, in a Chevy II wagon, it completed and finished the event. It has been in Leo Santucci's 1954 Studebaker drag car for a while, running the best of a 8.18 @ 170.03 in the quarter, so it has already been fast, but we are looking for the 7 second time zone, to show the world it is the Fastest Atlas 4200 in the World.
