But the whole thing was handled too naively – they had figured out the importance of aerodynamics, but the attempts to implement this in actual designs didn’t bother with the details and the makers were "too idealistic". Before the final shape of the GT was determined, dozens of airflow guides were tried with their respective scoops and mouths and fins, so that in the end a comparatively chunky device was left, however, it was perfect for being painted with the blue and orange stripes of the sponsor Gulf Oil.
The problem with racing in general and specifically in Le Mans is always the same. At a speed of 300 km, the cars start to misbehave, and at 330 km the physics go crazy. This doesn’t matter for Formula 1. Even at 300 they stick to the streets in full. They do not need 330, controlled cornering is much more important.
But the top was crucial for sports cars and prototypes, especially in the early days at Le Mans, when there were no chicanes on the 6-km stretch. If pushed to its limits, the car became an aircraft at some point, and in between there was a whole circus of physical absurdities. A completely new car, designed to win, was therefore dependent on the drivers who would donate their bones before the air flow had even halfway been mastered (a few years later, it wasn’t much different with the Porsche 917) The whole thing played out even without the priming effects of higher mathematics from the underbody, which came to racing 15 years later.
As for the engines, Ford could stay relaxed given the marvels of Ferrari's 3.3-litre 4ohc-injection engines. They had decades of steamroller development behind them, they had experience with small blocks and big blocks, and pushrod engines, which could all take a deep breath and were accustomed to blowing away the elaborate trinkets of European watchmakers. Who would need 8,500 rpm, when 6,500 created quite a riot, in relative serenity? Ford experimented with capacity from 4.2 to 4.7 litres, and then – completely logically and to the delight of hard-core fans – they went for seven litres. HP figures from America were hit and miss, that is to say they were in the order of 500 hp.
This is not to say that the GT was an old-fashioned car. They had a surprising love for details, such as an unusually affectionate attitude to the psyche and physicality of the driver. They were given decent (even expensive ventilated) seats, ensured amazing cockpit ergonomics (including a striking giant wheel which reduced the effort). As drivers would often ride in the rain, even at a rate of 320 km, they bought fabulously expensive Boeing wipers, which allegedly cost the price of a racing engine, which was not $400,000 at the time, but a thousand dollars. Yes, one thousand dollars for a 4.7-litre engine, say the old recordings.
