This GMC cylinder block is precision-machined to ensure perfect fitment and compatibility with other engine components. It also features a cast-in cylinder head gasket surface, providing a strong seal between the cylinder block and the cylinder head, ensuring optimal compression and combustion efficiency.

In addition to its robust design, the GMC 12674846 cylinder block also includes several features that make it easier to install. These include threaded bore liners, which simplify the installation process by allowing the use of standard engine bolts, and a machined surface for the crankshaft position sensor, ensuring accurate engine position sensing.
