The largest and most powerful piston aircraft engine ever built

There was another, the Lycoming R-7755

What the world needs, it doesn't know it yet, is for Bob Lazar to strap that into a 1991 Honda CRX.

Before anyone claims there is some exotic reason for the helical arrangment, it's done that way for packaging. You can get more cylinders in the same space if you slightly twist each layer in relation to the layer in front of it. There might be advantages in airflow with the helical design but that's not why they did it. It's just to make it shorter. This was designed originally for the B-50. For those not familiar, a B-50 is just a beefed up B-29 designed to carry a fat man nuclear payload for Strategic Air Command.

Can you cut and switch the clips even faster so that it's even more a blur?

Crazy how far we have come when it comes to aviation

I have a few NIB valve covers for one of those.
