In an internal combustion engine, the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single ...
VIN on a Chinese moped VIN on a 1996 Porsche 993 GT2 VIN visible in the windshield VIN recorded on a Chinese vehicle licence. A vehicle identification number (VIN; also called a chassis number or frame number) is a unique code, including a serial number, used by the automotive industry to identify individual motor vehicles, towed vehicles, motorcycles, scooters and mopeds, as defined by the ...
The short block represents the major wear items of an engine: piston rings, and potentially a rebore of the cylinder bores or replacement liners, together with reground bearings on the crankshaft. Although replacing the rings or bearing shells was at one time considered typical garage work, the need for a boring or crank grinding machine now ...
1962 – The block's cylinder wall casting was revised to allow four-inch bores, and the 327-cubic-inch version of the engine, using this bore diameter and increased stroke, was introduced. 1967 - The oil filter mounting received an adapter and machining to allow the use of spin-on filters; canister mounting was possible by removing the adapter.
Still using a revised variable geometry turbocharger, it also features an EGR cooler to lower NO X, with a bypass valve to avoid increasing hydrocarbon emissions before the engine reaches operating temperature, and a cylinder head optimized per Nissan's MK (Modulated Kinetics) combustion method.

Bore and stroke is 86 mm × 78.5 mm (3.39 in × 3.09 in). It is an aluminum block with cast-iron cylinder liners and aluminum heads. Output has varied depending on the application but typical was 200 hp (149 kW) at 5800 rpm with 190 lb⋅ft (258 N⋅m) of torque at 4850 rpm.

Two cylinder-head designs were developed, one similar to the 351W, but with larger ports and valves, and the other with very large ports with canted intake and exhaust valves similar to the big-block Ford 385 series V8. Sales, marketing, and product planning favored the canted valve design, as it was viewed as more innovative.
