Factory Stroker Crankshaft ?

Is it possible to offset grind a factory LSX Nodular Iron 3.62 crank for more stroke . I seen older pontiacs do this for more cubes . If its possible how much would this cost , who can do this , and how much extra stroke could I get ?

I built that 393 motor in the engine masters... Thats me in the pics! We used to offset the stock crank from 3.62 to 3.72" with no problems into the high 9's/low 10's
