'Jackie Stewart will not know until this morning which car he will drive in today's big race at Oulton Park. After a day of frustrating breakdowns his six-man team of mechanics worked through last night to change the engine of his Tyrrell-Ford. If the changeover cures the troubles - mainly due to metering failure in the fuel injection system - Jackie is almost certain to race the car today. The world champion is anxious to try the car in a competitive race before the Italian Grand Prix at Monza on September 6.' Jackie Stewart was Formula One racing Champion three times once in 1969, 1971 and 1973. He retired in 1973 and became a spokesman for safety in F1. He received a knighthood in 2001.
