Allison was born December 3, 1937 in Miami, FL. He entered his first race as a senior at Archbishop Curley-Notre Dame High School in Miami. Since he was only 17, he had to have his parents' permission so he thought when his mother said ok, it was forever, but she thought it was for only one race.

The 1973 National 500 was held October 7, 1973 at Charlotte Motor Speedway in Concord, North Carolina. The first three cars to cross the finish line after the scheduled 334 laps (501 miles) were driven by Cale Yarborough, Richard Petty, and Bobby Allison, in that order. Again, these facts are not disputed. What is disputed, is the legality of the first two cars' engines, recounted in Jim McLaurin's book "NASCAR'S Most Wanted", in the chapter "Fudgin' With the Rules": In the 1973 National 500 at Charlotte Motor Speedway, Allison protested that the engines in winner Cale Yarborough's and second-place Richard Petty's cars were over-sized. NASCAR inspected all three of the top finishers, and Allison's engine fit the cubic-displacement specs. Six hours after the inspections began, NASCAR technical director Bill Gazaway told the press that the results were being sent to headquarters in Daytona for a final decision. Monday afternoon NASCAR released a statement saying that, because the inspection facilities at Charlotte were inadequate, the pre-race inspection numbers would be used-when all three cars were legal and that the results would stand. Allison threatened both to quit and to sue. It was not until after a private meeting with NASCAR President Bill France, Jr., a week later that Allison was assuaged. Speculation was that Allison had been bought off. Allison wouldn't confirm or deny it, saying only that he had "received satisfactory restitution". The results were never changed. 1973 was a transition year in NASCAR. Teams could run a restrictor plate-equipped 7-liter engine or a 5.9 liter engine without restrictor plates. A decade later, Petty's over sized engine at the same race resulted in new NASCAR rules being implemented against oversized engines, including the possibility of twelve-week suspensions for the offending engine builder, driver, and car owner.Answer this question using a quote from the following article:
