Case Clearance for Connecting Rods
While I did my dry assembly, I found that the connecting rods bolts hit the inside of the case when I tried to spin the crankshaft all the way around (due to the "stroker" crank, there is a greater distance between the center line of the main crank journals and the center line of the connecting rod journals).
The point of contact was this stiffening gusset cast into the top of the case (if you look very closely, you can see two little shiny marks where the rod bolt contacted the gusset):
With a file type bit on a die grinder, I ground some of that material away:
And then did the other side. Now the case halves are ready for final washing/cleaning.
