K cars), with all production subsequently sourced from Pillette Road Truck Assembly. Model changes For 1980, the windows were revised, with sliding side doors receiving a single-pane window (in line with the single-panel rear door). For 1981, the B-series van underwent a major rebranding, as Dodge retired the Tradesman and Sportsman nameplates in favor of Dodge Ram Van/Wagon; the B-series nomenclature was revised to B150/B250/B350. Derived from the B150, the Mini-Ram was a higher-trim passenger van with a larger fuel tank. Through the 1980s, the model line underwent relatively few changes. The introduction of the Chrysler minivans marked the retirement of the Dodge Mini Ram Van and Plymouth Voyager for 1984, as both nameplates were adopted by the minivan line. For 1986, the grille and badging trim were revised in line with Ram pickup trucks. In a safety upgrade, outboard seating positions received 3-point seatbelts for 1992. For 1994, the model line underwent its most substantial revision since 1978. Distinguished by new front sheetmetal (adopting a grille styled in line with the redesigned Dodge Ram pickup trucks), the body shell underwent structural enhancements to improve crash protection. To modernize its appearance, the chrome window trim and chrome door handles were deleted, with brightwork limited to the bumpers and grille.

Powertrain details For the second-generation Ram vans, several changes were made to the powertrain line. After the 1978 model year, Chrysler retired its big-block 400 and 440 V8s for all its vehicles, leaving the 360 V8 as the largest engine offering for the continued production of the model line. The long-running 3.7L (225) Slant-Six was retired in 1988, with a 3.9L V6 replacing it as the standard engine offering; shared with the Dodge Dakota, the V6 was effectively ¾ of the 5.9L V8. The same year, the 5.2L V8 adopted fuel injection, with the 5.9L V8 doing so for 1989. For 1992, Dodge introduced "Magnum"-generation engines, as the 3.9L and 5.2L engines adopted multiport fuel injection (the 5.9L V8 followed suit for 1993). For 1980, the 3-speed manual
