Arrington Peformance CNC Engine Block Decking & Cylinder Boring

We mean precise. The cylinder bore is accurate down to the tenth of a thousandth of an inch. (.0001") Cylindricity and concentricity are keys to high horsepower HEMI engines. If your cylinders are out of round or alignment is off, when force is applied to the piston through combustion or boost you set yourself up for failure. This CNC procedure ensures alignment of cylinders relative to the mainline, and aligns cylinder bore centers with companion cylinders.
