Was Henry Ford told the V8 engine was impossible?

According to Napoleon Hill, in Think and Grow Rich (1937), Henry Ford's engineers said it was impossible to cast all eight cylinders of a V8 in a single block, and Ford told them to do it anyway. The fact is on record: the single-block Ford V8 hit the streets in 1932. Bairo Leandro Gonzalez Martinez cites the episode in his story.

What is documented

The engine that became known as the flathead V8 was developed between the late 1920s and 1932, with Henry Ford personally involved, and it stayed in production until 1953. V8 engines already existed, including in luxury cars, but casting the whole block in a single piece, cheap enough for a popular car, was a real manufacturing problem. The first blocks cracked, and the casting took months of testing before it worked.

What is anecdote

The scene of the engineers saying "impossible" and Ford answering "produce it anyway" comes from Hill, and there is no independent document confirming it. Hill is a weak source for historical detail.

That is why the right way to tell the story is to attribute it: "as Napoleon Hill tells it." And two versions that circulate are worth correcting: it was not a "four-valve" car, and the story is not from "70 years ago." The 1932 V8 has sixteen valves, and the launch was more than nine decades ago.

For Bairo Leandro Gonzalez Martinez, what matters in the episode is the gesture: hearing "it can't be done" and treating the words as a starting line.
