According to my machinist, the bank that is being moved not only gives me more material on the thrust side but it is correcting the factory position of the bores in relation to the crank centerline. Due to core shift and mass production what Pontiac did was good enough for a production vehicle. My machinist is blueprinting my block and correcting the bore position. Just so happens this gives my more material on the thrust side. Many have suggested I should of went with a .030 overbore and maybe they are correct. I am not sure if the .030 makes much difference one way or the other. Based on the sonic test by moving the bores to the correct position and going .060 over I will have about the same material on the thrust side as if I just bored it .030 over.
