The stock V8 rods I have seen were slightly different and I think the Lunati rods in my son's 406ci Chevy were also slightly offset. I've also read about that somewhere and I'll see if I can dig out the article. As far as aluminum (race) rods are concerned, I'm sure you're right. Maybe the offset isn't a big issue in a race engine but perhaps has an impact if you're trying to get 100K+ miles from a daily driver? Let me see what I can dig up but the offset issue was one that was raised by the folks at K1-Technologies regarding the useability of SBC rods in the 250ci six.
