"With the change to the new 3-litre F1 regulations at the start of 1966, Gurney decided to go it alone and start his own F1 team, the first such US effort since Lance Reventlow's abortive Scarab project at the turn of the decade.
He established All American Racers at Santa Ana, California, to field cars at both Indianapolis and in the World Championship. He started the latter programme with an uncompetitive 2.7-litre Climax-engined car, but the sleek Eagles would soon be powered by Weslake V12 engines and, thus equipped, Gurney stormed to victories in the 1967 Race of Champions and Belgian Grand Prix. Dan would later admit that the Eagle- Weslake was a dramatically underfinanced project: 'We had minimal backing in every area. I think Weslake can be proud of their part in the organisation although I think they would concede their end of the operation was a little shy, even though they were working miracles.' The first Weslake V12 cost $280,000 and each of the six engines built were hand- fettled. Off track, it was a difficult time for Dan. He was attempting to deal with a failing marriage and, rattling back and forth across the Atlantic like a yo-yo, attempting to keep the F1 programme alive whilst at the same time running an Indy car programme, which was taking a disproportionate amount of his time.
The Eagle F1 project finally died in mid-1968, Gurney's enthusiasm for motor racing in general having received a severe dent when Jim Clark was killed in April of that year. In the wake of Bruce McLaren's sad death in the summer of 1970, Dan was drafted back into the USA and never raced again. For the next decade a succession of Eagle Indy car programmes continued, but they too had vanished from the scene by 1983."
