SDPC pictures of the newly revised LSX block The newest revision of the GM LSX Bowtie block has been released and we have them in house right now.
Main features of this revision are:
-Improved metallurgy that results in upwards of 50% increase in tensile strength throughout the block.
-Reinforced deck with strengthened water passages and bolt holes
-Revised cam oiling passages that allow clocked cam bearings to optimize camshaft oiling in the highest performance applications with huge spring pressures and high loads.
Here are a few pictures of the blocks (there is a thin layer of oil covering all machined surfaces):

All of the cylinders in that picture are like that. The cylinder wall is thinner because of the bolt hole. If the camera was more centered on the block, you would see they would be thinner on the right side of the cylinder as well by the other bolt hole.

I've posted what I know was changed. Obviously, we have not built anything with them yet since they are brand new. From what I see, I see a much better product so far.

I have no first hand experience with this, but I monitor threads about core shift. Will be going with some kind of aftermarket block on the next build.
