With big block strength, and a stroke shorter than a 350 Chevy, how can these things not rev to the Moon?
How high it revs will depend on the head flow and induction along with cam design. The short stroke and long rod ratio make the 400 gentle on it's guts at high rpm's even with heavy pistons and rods. Given the same basic induction and cam a small bore long stroke 59 383 (4.03 x 3.75) will rev higher than a .030" over, stock stroke 400 before it runs out of air, it's the overall cubic inches that draw a given amount of air, not the stroke.
