The Tri-Five Chevrolets of 1955 to 1957 introduced the small-block V8, the first V8 in a Chevrolet since 1918. For 1957 the line came in three series, with the Bel Air above the Two-Ten and One-Fifty. Bel Airs carried a ribbed aluminum insert in the tail fins. This one is a 1957 Bel Air convertible built as a lowrider, with custom paint and hydraulics.
