Is off center engine normal on S30?

[Bonzi Lon]

I was under the hood doing some measurements and laid a straight egde between the frame rails at the crankshaft pully face and to my surprise found the center of the crankshaft to be 1/2 inch above the top of the frame rails. Then I measured from each frame rail to the edge of the pully where the straight edge intersected. Passenger side was 9 7/8" the drivers side was 10 1/4". Clearly a full 3/8 inch to the passenger side. Is this within normal tolerances?

The engine was offset to one side at the factory. I'll try to find the measurements tonight.
