Response to Is it possible to get 4.125" stroke from an offset ground 391 crank?

I'm pretty sure stock journal size should be 2.4384. I doubt you could grind it to 0 on one side so with a little fudge factor you might get to almost 4.118
(without being .010 under) You could always mock it up in your block with a rod and piston and measure the stroke
