An unusual face was in pole position for this Forward Trust round with Dave Morgan standing in for Dave Walker in the GLTL Lotus 69 and he took an immediate lead from pole position at the start from the AIRO cars of Alan McCully and Alan Jones. Other front row starter Roger Williamson was in immediate trouble when his throttle cable broke and he lost four laps in the pits. Also suffering was Randy Lewis who had a huge spin at Hanger on lap one when he lost control of his Brabham BT35 when in sixth place. Fourth place was an on form Jody Scheckter (EMC) leading David Purley’s Brabham BT28, Scheckter wasn’t content with fourth and he overtook Jones going into Club on the second lap and he did the same thing to McCully on the third lap.
Within two laps the EMC was on the tail of Morgan’s leading Lotus but Scheckter had to be careful when found the two cars of Jones and McCully had followed when he had passed them. David Purley found himself in difficulties at Village on the fourth lap when he spun off and removed his nosecone, he made it back to the track but continued a long way down.
On lap 5 Jones went ahead of Scheckter but the EMC soon regained the place but the battling between the two cars allowed Morgan to eke his lead out to five seconds. Scheckter had a slight moment at Club allowing McCully to overtake the EMC and the Lotus driver was able to draw away when Scheckter got involved with the several laps behind Williamson. Alan Jones squeezed past Scheckter at Brooklands on the last lap and as Jody tried to outbrake the Brabham into Club, the EMC locked its brakes and spun off into the barriers.
At the end of the 10 laps Morgan took the victory form Alan McCully and Brian McGuire who started from the back row with a ten second penalty.
