Interesting...those dimensions are VERY similar to om603 (except .97 3.5L version...only about 145mm length cL to cL) rods...so those m121's could likely be adapted/modified to fit the newer series engines as well...Pauter makes a really good rod though. I have them in a 4.9L Jeep stroker that I built a few years back.
I'd love to get a set of Mahle Monotherm (forged STEEL) pistons and a set of Pauter Titanium rods...just cannot justify the cost...likely more than the whole car is worth!
