400/426 Stroker. Ever heard of one?

So the rotating assembly has cost me $1600. It’s half the cost of a 440 source stroker kit. In addition to gaining 26 cubes, it also maintains a large over-square configuration. I’m hoping this adds to the high revving nature I’m planning/aiming for.
Is the 400 stroke the same as a 383? (Shorter than a small block Chevy) what is the stroker crank stroke.
