make the tall Gurney fit comfortably at the wheel. Their efforts produced a V12 that was smooth and powerful. At Monza, an insight into the future of engine design was seen for the first time. The engine had four valves per cylinder at a narrow included angle (thirty degrees) that allowed a single cover to enclose both the close-spaced camshafts on each bank. The sixty-degree-vee layout had a larger bore than stroke (72.8 X 60mm). Gurney's program ran out of money in 1968 and by the end of the year he returned to the United States to concentrate his efforts on the more successful Indycar program, in which Bobby Unser had won the Indianapolis 500 and the 1968 Indycar Championship. A non-works version briefly appeared with privateer Al Pease in the 1969 Canadian Grand Prix, but Pease became noticed for all the wrong reasons and made history as the only F1 driver ever disqualified for being too slow. USAC & CART Champ Car During the USAC years, the Eagle chassis was very successful in the late 1960s and 1970s. Eagles won 51 Champ Car races, including the 1968 and 1975 Indy 500's won by Bobby Unser and the 1973 race won by Gordon Johncock. During this two-decade period, Bobby Unser, who drove Eagle cars for most of his teams, joined AAR as the sole driver, winning the 1975 Indianapolis 500. Unser also claimed 22 wins and 52 podiums with Eagle cars. After Unser's departure from the team for Team Penske, All American Racers started to lose their edge in IndyCar competition. Mike Mosley won a few races for the team before being dismissed at the end of 1982. By 1984, AAR merged with Mike Curb's team to form Curb-All American Racers. After a two-year partnership with Curb, Gurney and Curb parted ways, and this marked the beginning of the end of AAR's time in IndyCar. The All American Racers team was inactive in single-seaters from 1987 to 1995 and returned in 1996 again building their own chassis and using new Toyota engines. However, this new effort, a combination of new and untested equipment, did not prove to be successful, never winning a race and collecting only occasional top-tens. The team ceased active racing after the 1999 CART season.
