LA 360 maximum overbore ??

Any LA that is going to be over bored more than .040 SHOULD be sonic tested for core shift. All of my strokers, 408 & 416 blocks were sonic tested to be SURE that the cylinders would stand the .060 bore that I require & I full filled the blocks with Hard Blok to help keep the main caps from walking. I DO NOT suggest .060 over bore on a street engine because of over heating problems, some have done it with success. My street engines usually turned into race engines, but that's what I enjoy. I have a friend who has some early 67-69 cast date LA 340 blocks that were bored 4.125, most of them ended up as door stops.
