Editing Buick V6 engine (section)

====LC4====
In response to rising gas prices, a larger {{cvt|4128|cc|CID L cc|1|adj=ri0|order=out}} version of the 3.8 liter LD5 V6 was produced from 1980 through 1984 and marketed as an alternative to a V8. The bore was enlarged to {{cvt|3.965|in|mm}}, yielding an output of {{cvt|125|hp|0}} and {{cvt|205|lbft|Nm|0}}. This engine was used in many large [[rear-wheel drive]] Buicks, and in some models from each of GM's other divisions, including Cadillac which offered the "big" Buick V6 in several models from 1980 to 1982 as a credit option to the troublesome [[Cadillac V8 engine#368 and V8-6-4|V8-6-4]] engine used in 1981 and early versions of the aluminum-block Cadillac [[Cadillac V8 engine#HT-4100|HT-4100]] V8 introduced in 1982. It was also the standard powerplant in the front-drive [[Buick Riviera|Riviera]] and [[Oldsmobile Toronado]] from 1981 to 1984. Additionally, the 4.1 block was used unsuccessfully at Indianapolis for racing. Its only weakness was the intake valve seals.{{citation needed|date=November 2024}} This was the first naturally aspirated GM V-6 to feature a 4-barrel carburetor.
