I just got the results of the block soundings on one of my
303 56 Fury engines. The machine shop is telling me I will still have at least 1/8th
inch of cylinder wall after boring the block the full 100 thousandths required
to run stock 318 pistons. I figured that is would be ok, since I had bored my
318 57 Fury engine to a full 4 inches (+.090) back in the late 50’s and
it worked out very well.
