Stock piston diameter 3.498 => 81.69 in3
.01 overbore piston 3.508 => 82.15 in3
(not exactly the same as swept cylinder volume, as the cylinders are slightly more, but this is splitting hairs...)
.46 in3 additional volume equals nothing in practise, but if your cylinders are worn a fresh hone with oversize pistons and rings (check if required for .01 over) will give you better sealing rings = less blow-by loss...
No re-jetting needed.
