How To Build A 4,300hp Aviation 'Wasp Major' In The 1930s?

Known as one of the largest living piston engines ever in aviation, this 28-cylinder marvel was one of a kind in real working aircraft out there. Pratt & Whitney managed to get things right and achieved noteworthy success with it. Although it came too late to be used in the war, it proved useful even after. However, during development things would not go as easy and engineers had to think outside the box to finish this challenging assignment.
