Hey Tom ,
Thanks for sharing ....at 2AM

Notice any cracks at all on top of block ? Those cyls look pretty smooth and can not see any ridge ring. Do you know history, as in how many miles on engine since .015 pistons, etc. LOTS of oil about, eh. A guy once told me...'yup, you want to see lots of oil covering things automotive, because that keeps things in good shape'. Hmm, looks like yours will be in good shape
