Hi, I have recently purchased a v8250 block with the pistons ,on inspection I realised that it has liners installed which looked to be in excellent condition and my first thought was to re ring the pistons and reassemble it, however on closer inspection the pistons are quite sloppy in the bores and I have been told that the liners are slightly oversize by .003" to .005". my question is, would it be ok to bore the liners and fit + .010" or + .020" pistons , Regards ,Terry.
Before you do anything, measure the pistons and the bore and check against recommended sizes, the pistons are not that tight in the bore when cold. With a 20thou oversize bore you are removing 10thou / side of the liner, you would need at least a liner thickness of 20 thou after a rebore probably 40thou for reliability.
