The 6.2 L (379 cu in) V8 is the main variant of the Boss engine. The V8 shares design similarities with the Modular Engine family such as a deep-skirt block with cross-bolted main caps, crankshaft-driven gerotor oil pump, overhead cam valve train arrangement, and bellhousing bolt pattern.
In 1968, the small-block Ford stroke was increased from 2.87 in (72.9 mm) to 3 in (76.2 mm), giving a total displacement of 4,942 cc (4.9 L; 301.6 cu in). The connecting rods were shortened to allow the use of the same pistons as the 289. The new 302 replaced the 289 early in the 1968 model year.
The smallest-displacement engine of the 385 engine family, the 370 was introduced after the 429 and 460, replacing the 361 cu in (5.9 L) 360 Truck (FT) V8 in 1977. . Sharing its 3.59-inch stroke with the 429, the 370 was designed with a downsized 4.05-inch bore (shared with its predecessor and the 3
The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
The Ford Cologne V6 is a series of 60° cast iron block V6 engines produced by the Ford Motor Company from 1962 to 2011 in displacements between 1.8 L; 110.6 cu in (1,812 cc) and 4.0 L; 244.6 cu in (4,009 cc).
Crankshaft: Forged; Knock sensors from the Ford Boss engine; Siamesed cylinders with saw cuts between cylinders to increase cooling capacity; Variable oil pump for fuel economy [7] Because the engine uses overhead valves actuated by pushrods, it is smaller than many of the overhead camshaft Ford Modular engines, and can be fitted to older cars.

Internal changes to the engine included an engine block and cylinder heads modified to accommodate increased coolant flow, a fully counterweighted forged crankshaft, a billet camshaft with revised cam profiles, and hypereutectic alloy pistons, along with a reduction in the compression ratio to 8.2:1.
