Pinewood derby cars start from a $3 kit (below).
After carefully studying the car in the film, I created a scaled cutting guide that is adjusted to the size of a derby block. You can download it by clicking the image here:
You can print out this PDF and it will be perfectly sized to the standard wooden block. The dashed lines should line up with the wheelbase.
