GM also made extensive use of economies of scale for the LS: with the exception of the 4.8L and 7.0L engines, all variants used the same 3.622" stroke (with most of those variants using the same basic crankshaft casting), the 4.8L and 5.3L variants utilized the same block casting, and several variants used the same length connecting rod.

The 1970 model year Camaro had a 250 hp (186 kW) high-performance two-barrel Rochester carburetor. In 1971, it dropped to 245 hp (183 kW), and net performance further dropped to 165 hp (123 kW) for 1972 and 145 hp (108 kW) for 1973–1976. It was basically the two-barrel version of the L48 350. It was produced until the 1976 model year.

The LG5 ("V-code") was a special 3.1 L (3,135 cc) turbocharged engine produced with McLaren for the 1989 and 1990 model years. It featured the same multiport fuel injection intake manifolds and throttle body as the LH0, and produced 205 hp (153 kW) at 5200 rpm and 225 lb⋅ft (305 N⋅m) of torque at 2100 rpm.
In 1986 and 1987, the 4.3 L (262 cu in) engine saw engine design upgrades similar to the Chevrolet small block V8. In 1986, the rear main crankshaft oil seal was changed from a two piece to a one piece seal. Some 1985 model year vehicles would have a 1986 engine due to service replacement – cylinder blocks were shipped with oil pans.
Power consumption of the water and oil pumps were reduced, and the piston rings, cylinder bores, and crankshaft journals were designed to minimize friction. [1]: 3–5 To maximize durability the engine block was made of cast iron with five main bearings, rather than the relatively fragile cast aluminum block used by the 2.3-liter Vega engine ...
The Chevrolet Stovebolt engine is a straight-six engine made in two versions between 1929 and 1962 by the Chevrolet Division of General Motors.It replaced the company's 171-cubic-inch (2.8 L) inline-four as their sole engine offering from 1929 through 1954, and was the company's base engine starting in 1955 when it added the small block V8 to the lineup.
