i took my block to Karl the other day and he measured the bore at 91.8mm i.e 1mm oversize. i have just removed my pistons from the rods and can't see any markings whatsoever to indicate their size i presume any oversize piston would be marked up as +.25 etc etc

all mine have is a code on the underside ,looks like : 90p44w2+

..oh and a nice bit of valve contact on top..unusual for a cossie eh

any help as to what size these pistons are ( do oversized normally come with markings?? ) oh and i haven't got my vernier with me at the mo
