It features a cast-iron LSX block with 6-bolt, cross-bolted main caps and comes with OEM-type hydraulic roller camshaft. The cylinder heads are LSX-LS7 Port Aluminum with a 70cc chamber volume and 2.20\"\/1.61\" valves, utilizing an LS7 rectangular port intake pattern.\n\nThis crate engine does not include an oil pan, and the valve covers do not have provisions for mounting ignition coil brackets; aftermarket or custom relocation brackets are required. Additionally, it features an 8-bolt crankshaft flange that may necessitate an adapter for certain transmissions.
