A Regular Production Option (RPO) is a 3-digit standardized code used by General Motors to designate vehicle options & modifications. RPO codes designate how a vehicle is built, and they've been used on dealership order forms and in assembly plants since at least the 1950s (see Corvette C1).

An updated 4L60E, the 4L65E (RPO M32), was phased in the 2001 model year when coupled behind the 6.0 Vortec. Five-pinion front and rear planetaries, along with an additional 3/4 clutch allowing 7 clutches in the input housing and induction hardened input shaft assembly, were improved to withstand up to 380 ft⋅lb (520 N⋅m) of torque.
The "LS" nomenclature originally came from the Regular Production Option (RPO) code LS1, assigned to the first engine in the Gen III engine series. The LS nickname has since been used to refer generally to all Gen III and IV engines, [14] but that practice can be misleading, since not all engine RPO codes in those generations begin with LS. [15]
LD5 was the RPO for engines with chassis code "A", LD7 was used for the 1977-only VIN code "C" engines. One quick idea was tried by Buick engineers—taking an old Fireball V6 picked up at a junkyard and installing it into a 1974 Buick Apollo. The solution worked so well that GM wanted AMC to put the engine back into production.
The Vortec 2200 (RPO code L43) is an OHV straight-4 truck engine. This engine is equipped with secondary air injection, and is flex-fuel capable. It is entirely different from the Iron Duke, and was the last North American iteration of the GM 122 engine. The 2200 uses an iron block and aluminum two-valve cylinder head.
