Ring sizes on stock l98 5.7 block?
I'm in a bit of trouble I just bought a re-ring kit. I kept the cylinderwalls and everything stock, I didn't bore or any of that. And the rings I ordered (I ordered Standard size) and the rings went in fine, EXECPT the LOWER COMPRESSION ring. So I'm going to call the company that I bought them off of and re-order the rings I will need, only I don't know what the size on the lower compression ring is? Would any of you happen to know the size on the stock L98 piston? Thanks

have you ever put on rings before? just curious, 'cuz the lower ring is huge and sloppy compared to the rest, has a bigger gap, and is a PITA to put in. (unless you know "the" technique.)
Seems strange that the tops rings in the box are right, and the oil ring isn't....

Both compression rings are 5/64" thick. The oil ring groove is 3/16".

I like Sealed Power E251K. Pre-gapped, moly-faced top ring, available in overbored sizes.
