Look closer. Also, the rods are offset and need to be positioned with the notches towards radius on crank.

You can NOT just look at the spurt holes.


If there are no notches on rods (aftermarket) you need to check how the bearing sits in the rod, the side with more room goes towards radius on crank.


Your 1967 and earlier rods are cast I-beams. 1968 and later rods are reinforced at the big end as shown on my picture.

Thank you for the visual, it helps, it is hard to see the Beveled edge/champhor on the large side of the Rod, perhaps I should pull the Bearings out and inspect the area.

One easy way to determine the side of the Rod that goes toward the radius of the Crank or that faces each other is to associate the Rods marker @ the top of the Rod Pin area that has the two-digit number over it and orientate that visual, that I understand and point that out to me, the marker faces inside adjacent to the Rod that shares a Rod Pin or outside toward the Crank Radius?

Mikes reply:

It seems to me that one side looks wider than the other with the Bearings installed in the large side of the Crank pin.

I will go back and study that again, but still answer the above request, that marker is in the location for a reason, so let's use it, please, to confirm the orientation of the surfaces in question.
