|Mecom Racing Team had in fact undertaken a season of USAC events competing in all the paved circuit races. (At that time the full USAC season included a number of races run on dirt ovals and the Pikes Peak Hillclimb for which the Lola was unsuitable).
Al Unser’s ‘Retzloff Chemicals Special’ finished all but one event and usually in the top half of the results sheet. Six top three finishes earned Unser fifth place in the Championship but that first win remained elusive.
At the final race of the year, The inaugural running of the Rex Mays 300 at Riverside, John Surtees took part in the only USAC race of his career driving the Bowes Seal Fast #24 car. Surtees retired on lap 31 with magneto failure.
