The 1965 Buick Skylark saw the introduction of an all new 400 cid
performance oriented motor. This represented a signifcant shift
in thinking for Buick executives. The addition of a large motor
to an intermediate platform such as the Skylark created the potential
for a powerful muscle car. In fact, within five years Buick would
be well known for building some of the highest horsepower cars to
ever come out of Detroit.
