But compression isn't the advantage they are looking for, is it??? I thought it was to have a better angle on pushing the crank down on the power stroke ???? That was my understanding of the old trick from DC... I could be wrong.
No, right. Someone was quoting one of the other guys who said that it also somehow "magically" raised the piston in the bore. You're absolutely correct though, just the flip itself is "supposed" to reduce some friction and free up a little power. That's what I've heard from TONS of people through the years. I have some old dirt track friends who have SWORN by it for years......and they were coincidentally some of the best racers out there.
