So, after removing the 6 main case bolts, and undoing 20 fasteners around the perimeter and elsewhere, I am ready to split the case. But the seam is resisting.

I'd bet something like this could split the case halves.....

Did you get the bolt that goes through the windage tray? It is between the two cylinder spigots in a recess.

It was the same one I didn't see when I first split a case.

All the bolts were out (I counted them at least a dozen times).

I tried the method of prying between the front shaft impeller flange and the front seal. After a gentle pry, the seam opened up along the front, but the back was still stuck. I resorted to some plastic wedges (door frame shims), and that did the trick.

But the bolt-on cam is not stock, right?

But the number 2 bearing shows a bit more wear. This is the worst one.

All the crank journals look great.

After a quick measuring session, the mains are about 2.3520 inches, suggesting these were ground one step undersize.

And the con rod journals are about 1.959 inches, two steps undersize.

A bit more tinkering today, starting with removing the oil pressure relief valve. Step one was to make a tool to fit the slot profile in the cap.
