Ok, I already apologize for my post, First off, I know nothing about fords, and all I know is that I have a 80's I think 87 efi 302, it has a roller cam. I'm not sure how to read the castings, i'm still researching on that.. I got it from a junkyard and going to rebuilt it.. I ordered rings and bearings for it, the problems lies at the oil ring is too big to fit the groove...the rings I got are sealed power E-251x
"standard size rings for every 302 that shows up on autozone, O'riellys parts?"
