Good call mikedsilva, I measured the case bore and it's way out of spec. I'm pretty surprised as this engine has never been taken apart and everything was in such good shape. I thought the aluminum cases were solid.
I'm getting 65.045mm - 65.060mm which was a long way from the max spec of 65.019mm.
The funny thing is that when I do the calculations with the bearings I measured (all very consistent at 2.495mm) and crank journals (all on the lower edge of the spec ~59.972mm) it indicates that I should have a clearance of nearly 0.1mm or 0.004". The plastigauge was showing between 2.5 and 3 thousandths.
At any rate, I'm going to send the case to Ollie's to have it line bored and I'll have the crank cross drilled while I'm at it.
