Terry,
You are definitely correct that the rod is MC9 or newer. 47903, if I'm not mistaken. This is not a pedigreed, factory built MC10, it is a clone, with parts from a variety of sources, hahaha. It's been a learning experience.
I understand your point that the centerline of the rod is constant. I have assumed that there might be a tolerance range for the position of the rod's bore. If a factory team engine builder was hand picking parts, what might he think of that one? Good? Bad? Indifferent? Go fish?
Torque,
Good eye! I hadn't even thought to inquire about a detail like that. I saw that notch in the 3rd port area of the piston skirt, but I assumed it was for clearance in the area of the side cover's main bearing. I've never thought much about it before, but is third port timing of much influence? If it hasn't been 9-ported?
Also, the piston is marked for MC6. Any concerns or comments on that?
