Stock bore = 3.339in
stroke - 3.465 in
displacement = (3.14/4)*(3.339*3.339*3.465*4) = 121.3in cubed
with a .030in bore
displacement = (3.14/4)*(3.369*3.369*3.465*4) = 123.5in cubed
Wow a whole 2.2 cubic inches or 0.036 liter
For the miniscule displacement increase I wouldn't do it if you planning on running FI on it later. .020in max on a stock block if you're going to force fead later on.
