It is possible that a hairline crack in the engine block of a Chevy 5.7L V8 engine could cause the engine to sputter and turn off. A hairline crack in the engine block can allow coolant or oil to leak into the combustion chamber, which can cause the engine to misfire and sputter. If the crack is large enough, it can also cause the engine to lose compression and turn off.
If you suspect that your Chevy 5.7L V8 engine has a hairline crack in the engine block, you should take it to a mechanic for diagnosis and repair.
