Chrysler seemed to specialize in doing the impossible. When they went to make radar units, then brand new technology, the scientists told them they had to be made by hand, there was no other way to get the parts accurate enough. In 2 months they were stamping them out on fender presses by the thousands and mounting them on Dodge truck chassis, with a special generator driven off the truck's engine. During the Manhattan Project they needed miles of pipe for the uranium refinery at Oak Ridge. The only material that would stand up to the acids involved, was pure nickel. Too bad it would have taken the world's production of nickel for 2 years to make it, and they didn't have it. Chrysler invented a new way to make nickel plated pipe that would do the job. Chrysler had the job of building tanks, to be powered by motors built by Ford. Chrysler got them in production so fast the motors were not ready, and would not be ready for 6 months. So they invented their own engine using off the shelf Chrysler flathead six industrial engines, 5 of them bunched together like bananas all driving a common drive shaft. Worked fine. They also developed a 2200HP V12 hemi head aircraft engine that never saw production because a) the war ended and b) the new jet engines made piston engines obsolete. But what they learned on that engine may have gone into the Chrysler hemi V8.
