291 with sleeves, youll be OK!! 301 with no sleeves, your OK too!! the 263-301 had the same crank and rods, same stroke, just a bigger bore piston. .060 over the 301 piston specs, and you will have problems over time,,, but at STD bore 301,, 3.8125 bore,, the engine can live for a long time and not risk block failure.
