im amazed how many guys dont understand that boring a block to the max isnt worth the hassle. you lose rigidity in the cylinder walls, which kills ring seal, and destabilizes piston to wall clearance. all for a few cubes...
you have no idea how many guys i've come across that tried to brag to me, "i have a 355, its better than a 350" congrats, you have freshly round bores- unless your machinist is a retard. and a 1.4% increase in displacement. big deal. installing the proper head gasket will net you better gains.
