Richard Attwood thought he had got it wrong. After having the fastest car in the 1969 Le Mans 24 Hours and being robbed of victory by unreliability, he now believed he'd been too conservative for the 1970 race.
Porsche was still searching for its first win in the French classic. The handling of its initially evil 917 monster had been sorted, but Attwood's main focus when asked which version he would like had been stability and reliability.
That's why he'd gone for a short-tailed 917K - with a straightline speed handicap but better handling - with a four-speed instead of five-speed gearbox and proven 4.5-litre engine. He also had Hans Herrmann, a safe pair of hands rather than pacesetter, as his co-driver.
