Editing Buick V6 engine (section)

====LC9====
A smaller version of this engine was produced in 1978 and 1979 for the Century, Regal, and [[Chevrolet Monza]]. The bore was reduced to {{cvt|3.5|in|mm|1}}, resulting in an engine of {{cvt|3216.3|cc|CID L cc|1|adj=ri0|order=out}} piston displacement. The ''RPO code'' was ''LC9''. Initially this engine produced {{cvt|90|hp|0}}, but in 1979 it received the same improvements in the cylinder heads as did the LD5, and therefore power increased to {{cvt|105|hp|0}}.
