We have seen both 112 and 117 in print.) They were only offered in black, the power plant was the 3.8 engine (but it was not turbocharged) and these are now the rarest Grand Nationals. (We were surprised to find that various Buick books do not agree on the production figure for the Grand National LeSabres. Production continued through December of 1987.Ī little known related fact was in 1986 Buick released another Grand National based on the new LeSabre front-wheel drive platform and only 112 were made. Because of increased demands for the 1987 model Turbo Regal, specifically the Grand National, Buick built an additional 10,000 Grand Nationals past the normal end of the model year. The horsepower numbers were slightly underrated on a cool day, they may be as high as 270 HP. They came with an intercooler, upgraded plenum, intake manifold and a few other improvements to produce 245 HP and 355 ft/lbs of torque. The 1986-1987 Grand Nationals had an upgraded version of the 1984-1985 turbo engine. They would run the quarter mile in the mid-15's. The 19 Grand Nationals came equipped with the new 3.8 litre SFI turbo engine, which made 200 HP and 300 ft/lbs of torque. In 1984 the Grand National was revived and made through late 1987. In 1983 no Grand Nationals were produced. They were powered by a 4.1 litre V-6 engine, all were painted two-tone grey and a large "BUICK" decal appeared on both rear quarter panels. The Grand National was first introduced as a mid-year model 1982-1/2. In.About the Buick Grand National Parts and Accessories V8 GAS OHV Naturally AspiratedĦ.6L 6555CC 400Cu.
