AFAIK; as far as I know.
The early rods are lighter than the 73 ups, maybe as much as 100 grams.
Therefore to maintain balance, you would need the matching pistons and crank.

Just for info.
Early rods: 726 grams
Later rods: 758 grams
All numbers measured by 2-3 people, including me; I have both sets here. Magnum rods are another matter.

in regards to my source in post #154,in the book, they didn't say where the numbers come from. But I see the same numbers in the Bulletin Book

Yeah understood. I just was relating someone else's measured height below deck for some '68 318 pistons from a post here on FABO, in which they seemed very confident. It lined up with my '68 273 piston numbers, so I ran with it..... but now you have made me question that again.
