Unless you have a cubic inch limit I'd say you got lucky.
Those giant Oliver billet rods are he77 for stout.

I have been buying part-used-up racing gear for the past few months and roughly half of the pistons have support rings under the oil ring because the pins are in the oil groove. If it's good enough for Sonny Bryant and Rousch Racing it's good enough for me!

As a side note, I have a half a set of Crower 7.1s with 4.360 diameter pistons that came out of a ford 460, I bought them for the rods. The rod/piston/pin/ring set weighs just a little more than 100 grams more than the bone stock rod/pin/piston/ring set from a stock 318!

I think some of the extremely conservative ideas found among Mopar lovers come from the unconscious attempt to justify the grossly overweight parts found in garden variety Chrysler Corp engines.
