Here's a story about one of the Ramchargers:
From what I was told, One of the Factory cars at one of the races was having some troubles, Carb I think. Allen Adams went over and solved the problem. The Factory employees who were there were impressed and that's how he became part of the Ramchargers. This is what I was told from a team member of a car he helped with in the late 60's-late 70's. This might be correct and it might not be.
