Default My Crappy lsx 454. Bad Core Shift. Paper Thin Cylinder Walls

My engine block is dimensionally defective having less than the advertised structural metal thickness. An important component of the engine block’s strength comes from having enough metal thickness to support a load. The industry standard and Chevrolet’s standard for cylinder wall thickness is a minimum of .200 thousands of an inch. Chevrolet’s own advertising for the lsx block states “maximum 4.250 bore at .200 minimum wall thickness”. My defective block had a smaller 4.185 bore, hence the remaining cylinder wall thickness should have been .2325. However the sonic testing that was performed post-mortem discovered a bore thickness as little as .177 which effectively cheated me of .0555 thickness of metal or using a simple analogy in dollars, I was entitled to $232.50 but only received $177.00 dollars. A shortage of $55.50 or 24 percent!
Clearly this engine block was defective even by Chevrolets own standards.
