Pistons tappered
I see from my measurements that the width of the piston at the wrist pin hole and then the top of the piston there is a difference of about .012", does this sound normal? At the wrist pin hole I measure 3.542", this is for a 2.7 piston, the size stamped on top is 89.97mm, that converts to 3.5421, the diameter of the cylinder measures 3.5435 which is spec. These have a little more than 100,000 miles on them.
