400/426 Stroker. Ever heard of one?

Same stroke. Reason for the 383 crank is to get a forged unit. When the rod journals are offset ground it increases the stroke from 3.38 to 3.545. Rod journals are now 2.2”
I love your build. Question. How much hp and rpm's do you think the 383 crank will hold after grinding and would a 440 crank ground the other way be stronger? I understand you would also have to grind the mains. Just wondering what the limits may be. Anyone's guess appreciated.
