Wheelbase Balance – McLaren Chevrolet M8F #10-72

There were three race winners in the 1971 Can Am Challenge Jackie Stewart won two races in his L&M Lola T260 while the rest all fell to Denny Hulme who won three races and eventual champion Peter Revson who won the remaining five in the fifth and final year of domination by the Traffic Yellow McLaren M8F cars.

The McLaren M8F was similar to the M8D raced in 1970 but had been upgraded by Gordon Coppuck with a 3″ longer wheel base, wider track, inboard rear brakes, sturdier gearbox to improve the handling and balance of the cars which had a choice of either 740hp 8.1 litre / 494 cui or just under 800 hp 8.4 litre / 512 cui Gary Knutson tuned alloy Chevrolet V8’s.

For 1972 the works McLaren team moved onto the M20 and sold on it’s M8F’s to the Young American Racing Team, one of which was driven to victory at Donnybrooke by rising French star François Cevert, while Trojan built up a number of M8F spec cars known as M8FP’s for customers to run.

The most successful M8FP customer in the 1972 Can Am Challenge was German Hans Weidmer who finished 8th from 21st on the grid at Edmonton driving chassis #07-72.

Helmut Kelleners sold his March 707/717 and raced a Trojan built M8FP #02-72 in various events through 1972 winning the Martini International at Mainz Finthen. In December ’72 Georg Loos won the Copa Brasil at Interlagos driving chassis #03-72.

By 1975 Peter Hoffmann had acquired #07-72 for racing in Europe and in 1976 returned the car to victory lane at Kassel Calden, Mainz Finthen and Ulm. Peter drove the car to three more victories at the Nurburgring in 1979 and 1981 and Hockenheim in 1980.

Today’s featured car #10-72 is seen with Charlie Agg at the wheel during practice for a classic race at Brands Hatch, #10-72 was never raced in period. Charlie Agg is the son of Peter Agg who revived the fortunes of Trojan and then Elva in the 1960’s.
