Crapped if I know. lol It becomes similar to how the 340s ran, but more exaggerated, since the bore size is so much bigger. Look at Pontiac motors, for example. Small bores and long strokes. Truck motors. Always in a Mopar's rear view mirror, too. I don't know stuff on a physics level, but I know the more surface area a piston has in terms of bore size, the more power can be made. The 400 has a LOT of real estate in terms of piston surface area. Think how good that is for air flow. Even with the short stroke, set up right, a stock stroke 400 can scream......same with a 383. 4.250 ain't no small bore size either.
