The one on the right to accommodate the shorter skirt steel piston which has the wrist pin mounted closer to the piston top, hence the reason for the longer connecting rod

I knew the difference; I just wanted the op to bring it out.

My question is how did the op come upon the occasion to have both side by side? Was there a rebuild of each in the shop?

A friend of mine has a business that specializes in the Ford 6.7 engine. That's where the rods came from. He commented that the new rod is much stronger then the old one.
The new rod/combo can take a lot more abuse the the old stuff.

Yes, I noticed that as well. The rod cap is "cracked" like a powder forged rod but the lack of any mold parting lines is unexpected. Maybe its the result of a better manufacturing process or some extra machining process.

Sintered rods are strong, but forged are stronger and sintered have other pluses too. Sintered are the main stay now, forged are for special applications

Correct. The new rods are not Carrillo's but are still a huge improvement over the old rods.
