This is being used in a street brawler. 440 Source 500 inch 440 stroker with the 5095 .055 over piston and their supplied ring CR9190-130 that are from Total Seal. I see on Total Seals web site, they call for more ring end gap on the second ring. The paper work that came with the pistons figures out to have the top ring at .020 and the second ring at .016. Who's correct?? Thanks Dan

Who's correct?? Thanks Dan The paper work that came with the rings is OLD(20+ years)... the top ring is right with the spec they call out for .004+ per inch of bore but the second ring MOST are making that larger than the first by .005(as in if the top is .022 make the second .027)

Thanks Dan None at all, those will work good Keep them square and make those readings with a tight fit Not loose, take your time on the last .002 Buy a good small sharpening stone to smooth the edges of the filed rings, top and bottom, front and back Last edited by Cab_Burge; 01/13/13 10:27 PM.
