Throwing caution to the wind I have installed the crank. Wrong main bearings or not I will find out if they will work. One theory is that the extra oil pressure from the deletion of the balance shafts will help offset the slop in the crank. Not to mention a little thicker oil.

Hopefully the piston rod bearings come in at spec. If the rod bearings don't, I guess I will just go with that too!
