  1. 5.0 piston ring size or part number???

    5.0L Tech
    My friend and i have been trying to find the stock piston ring size for a 91 5.0L HO V8. Summit has sent us the wrong rings twice when we asked for "stock replacement" rings. I was wondering if anyone could tell me the size or a part number of some mid-range piston rings. thanks! :headscratch:
