where to measure 273 ring gap in cylinder bore
Factory wear limit is .005" taper which equates to +.015" end gap , at .003" end gap increase per .001" wear , factory spec means .030" end gap is the wear limit . I rebuilt the standard bore 340 in my cuda in 2000 with .003 taper and .025 end gap and just a light hone , now 40,000 miles later no smoke , no oil use and still runs strong. You are overthinking it , put it together and run it.
