Input: Question: Why type of engine did the car have that Stewart used in his one off race in Can-Am? Passage:For 1970, Matra insisted on using their own V12 engines, while Tyrrell and Stewart wanted to continue with the Cosworth and maintain their connection to Ford, which conflicted with Matra's recent connections to Chrysler. Tyrrell decided to build his own car and in the interim bought a chassis from March Engineering; Stewart took the March 701-Cosworth to wins at the Daily Mail Race of Champions and Jarama, but development on the car stalled and it was soon overcome by the Lotus team's new 72. The new Tyrrell 001-Cosworth, appeared in August and suffered problems but showed promise. Tyrrell continued to be sponsored by French fuel company Elf, and Stewart raced in a car painted French Racing Blue for many years. Stewart also continued to race sporadically in Formula Two, winning at Crystal Palace and placing at Thruxton. A projected Le Mans appearance, to co-drive the 4.5 litre Porsche 917K with Steve McQueen, did not come off, due to McQueen's inability to get insurance. He also had a one-off race in Can-Am, in the revolutionary Chaparral 2J. Stewart qualified third, in what was the car's first outing, but brake failure ended his race.
