318 to 390 hp?

I know that it is possible to get 400 hp from a 360, the thing is i have a 318, i figure if i'm going to buy a new crank rods and pistons anyways i might as well go with the stroker kit, speedomotive sells them for about 1400 with rings and bearings, I know 400hp shouldn't be a problem with this kit if not more, i'm just looking for someone who runs it to see what kind of power is being made.
