I don't have a V8 rod to look at but I'm guessing there is not much of a "bevel" on the big end on the side that faces the neighboring rod and there is more of one on the "outside" to clear the crank throw fillet. The L6 rod has identical bevels on both side since it has to deal with the crank throw fillets on both sides. I suspect a V8 rod used on a L6 crank (even with the right 1.030" width) would bind on the one side and I don't know how the beam offset would affect operations - I'm thinking not good.
