Some of the oldtime racers actually preferred the splasher engines, claiming that the non-drilled crankshaft was stronger. Of course, our flathead V8 Fords outran them pretty regularly, regardless of which style they ran. The military-surplus GMC 270's gave us the best run for our money- - - -almost the same displacement, and gobs of torque, but their problem was too much wheelspin off the corners. By the time the Jimmy engine guys got hooked up, the Fords were halfway down the straightaway.
