From 1988 to 1991, another throttle-body fuel injection system was used for truck and van applications. 1983–1989 Chrysler Fifth Avenue 1981–1983 Chrysler Imperial (fuel injection) 1968–1981 Chrysler Valiant 1977–1981 Chrysler LeBaron 1979-1982 Chrysler New Yorker 1981–1983 Chrysler Imperial 1975–1983 Chrysler Cordoba 1976–1980 Dodge Aspen Dodge Charger Dodge Challenger Dodge Coronet 1968–1976 Dodge Dart 1977–1989 Dodge Diplomat 1991-1992 Dodge Dakota 1971–1972 Dodge Demon 1973–1976 Dodge Dart Sport 1970-1980 (Valiant) Dodge Super Bee (Mexico) 1971–1979 Dodge GTX (Argentina) 1978-1979 Dodge Magnum 1980–1983 Dodge Mirada 1967–1992 Dodge Ram Dodge Ram Van 1974-1992 Dodge Ramcharger 1968–1974 Plymouth Barracuda Plymouth Belvedere 1970–1976 Plymouth Duster 1967-1972 Plymouth Fury 1972–1989 Plymouth Gran Fury 1964-1974 Plymouth Satellite 1974-1981 Plymouth Trail Duster 1968–1976 Plymouth Valiant 1976–1980 Plymouth Volaré 1981-19??

Its block was bored out to but stroke left unchanged, resulting in the engine introduced for the 1968 model year. Anticipating higher loads resulting from racing operation, the engineers fitted a forged shot peened steel crankshaft instead of the cast nodular iron unit used in the 318. This also included shot peened hammer-forged steel connecting rods and high compression cast aluminum pistons with full floating pins. A 4-barrel carburetor was mated to a high-rise, dual plane intake manifold feeding high-flow cylinder heads Its big ports used intake and exhaust valves. An aggressive cam was fitted to take advantage of the much better breathing top end. The 1968 4-speed cars got an even hotter cam, but it was discontinued for 1969, where both automatic and manual cars shared the same cam. The engine was equipped with hydraulic lifters and two bolt main bearing caps, leading some to initially underestimate the 340's potential. The 1968-'71 340's compression ratio was 10.5:1, placing it near the limit of what was possible on pump gasoline during that era. The 340 also used additional heavy-duty parts, such as a double-row roller timing chain and sump-mounted windage tray. Power output was officially stated as
