| RE: 427 cyclinder wall thickness |

It's wise to sonic test prior to boring, as this gives you the option of "offset boring" if the engine shop supports that kind of machine work. This sometimes let's you choose a smaller bore.
Core-shifted wall thickness in the "reinforced" square-cast 427 cylinders can be as thin as .090" (if I recall Ron Millers post correctly) because the bulk of the head bolt stresses are handled by the heavy cylinder sections, leaving the thin sections the single duty of constraining the piston. The corners will still be around .250"+ thick.
