    I have picked up a early red 6.2 engine that is free of main web cracks. Is it possible that these engines will support to overbore to a 6.5's bore without getting to thin on the cylinder wall?

    Unfortunately, the early 6.2L castings (non-599 blocks) do not have thick enough walls to support the .075 over bore that is required to make the jump to 395 cubes. The walls would just be too darned thin.

    .020, .030, .040 over are all very popular, viable alternatives.
