If you want to build these first generation Olds Rocket engines, consider
getting in touch with some of the oldtimer nostalgia racers who have raced
these Olds V-8's. The famous "Woods, Stone, and Cook" 1941 Willys
was powered by a blown Olds. A lot of Willys-Overland gasers used the Rocket
block for power. Don "Big Daddy" Garlits knows some of these people
- he might be a person to contact. Southern California might be a place
to start looking!
Try 1-800-FAST-88S. They carry a lot of parts for the mid 50's cars.
