If they are not, what's the difference from both vehicles?Is the 1987 Buick Regal the same as the 1987 Buick Grand National?No, the Regal had a stock 231 V-6. The Grand Nat had a reworked 231 with a large turbo plus they only came in the color Black.Is the 1987 Buick Regal the same as the 1987 Buick Grand National?The grand national is based on the regal, it has the same chassis %26amp; sheet metal, but it has a reworked engine, transmission, suspension %26amp; brakes, you could describe it as a factory hot rod.

In the muscle car era most makes were available with uprated engines, brakes etc, the grand national is like a regal with all the performance options ticked.
