Not Ranked
An 0.050" overbore to 4.130" is going to remove 0.025" from the cyl wall, so subtract 0.025" from any of those dimensions on the chart to give you the wall thickness remaining at those points. eg 0.150" - 0.025" = 0.125" thickness. Then comes the 'fudge' factor, how much corrosion in the water jackets, were there any thinner spots than those points checked etc etc. I would play it safe myself & settle for less cubes, just BS everyone that its a 428.
