It was their first attempt at the event and the two cars which were entered finished second and seventh in the hands of Jim Clark and Dan Gurney.

Although they were not the first rear-engined cars built for the category, they were first to prove that the configuration was definitely a potential race-winner, and that the days of the big and heavy front-engined roadsters were numbered.

Based on the 25, it was a very similar car which differed principally in featuring a 4195 cc (255ci) Ford V8 with Weber carburettors producing 376 bhp (280 kW) through a Colotti T.37 gearbox.

It was slightly larger all round than the 25 and was fitted with offset suspension and Dunlop (front) and Halibrand (rear) knock-off wheels to facilitate rapid pit stops.

Later that year his engine failed at the Tony Bettenhausen 200, and then he crashed while testing at Phoenix International Raceway and succumbed to burns incurred in the accident.
