Editing Buick V6 engine (section)

The bore was increased to {{cvt|3.75|in|mm|2}}, and stroke increased to {{cvt|3.4|in|mm|1}}, increasing displacement to {{cvt|3692|cc|CID L cc|1|adj=ri0|order=out}}. Since the engine was similar to the popular small-block Buick V8—now with a cast-iron block and displacement of {{cvt|300|cuin|L|1}}, the engine was made cheaply at the same factory with much of the same tooling. This engine carried the RPO code '''KH''' for the 1964 model year and '''LH''' for 1965. In 1966, the code was '''MH''' and was renamed the ''Wildcat V-6''.  For 1967, the code was '''NH'''. This engine was used in Buick's intermediate-sized Special and Skylark models from 1964 to 1967 and Oldsmobile's mid-sized F-85/Cutlass models for 1964 and 1965, including the Oldsmobile Vista Cruiser and Buick Sport Wagon.

1964–1965 models featured a single barrel Rochester MonoJet, producing {{cvt|155|hp|kW|0}}. In 1966–1967, the 1-barrel was replaced with a 2-barrel Rochester 2GV, giving the engine a 5-horsepower boost to {{cvt|160|hp|kW|0}}.

The V6 was dropped after the 1967 model year in favor of a conventional {{cvt|250|cuin|L|1}} [[inline-six engine]] built by the [[Chevrolet]] division, and the tooling was sold to [[Kaiser-Jeep]].
