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.

Tim,
That is great how that all worked out. Since he is blueprinting your block, is he also doing your crank? The rod journal indexing is normally off a small amount.
