[JM 35 Sedan]

Tod, good luck with your project and thank you for stepping up to the plate to hopefully make this happen. I personally won't need a new block in what's left of my life time, but if we hope to keep future generations interested in the Flathead engine, someone's gonna need to make this happen.
When I rebuilt a '35, 21 stud engine, that had an early failure of a press-on fiber timing gear, I was told it was impossible to replace that gear without first removing the cam. I took this on as a challenge and successfully figured how this could be done and did it. This was nowhere near the challenge you will face, but the same principle applies, nothing is really impossible.
