Cool! I'm rebuilding the 454 in my Sea Ray and man what a job. My
question is, what is the most I can take of the cylinders and still
use stock pistons? Some water go into 3 cylinders last year and left
some pitting. After a lot of honing most of it is gone, but I thing
some machining will be necessary. I can post some pics if it helps.
Thanks.



use a piston and push a ring down into the bore. measure the gap and
compare to spec.
im guessing if you "honed" pitting out of the bore you are going to
need to oversize.
