Chrysler announced in January 1956 that it would make that years Indy 500 pace car. The division created a new model for the occasion and unveiled it at parties in New York, Los Angeles, and Indianapolis.
The new car was called the Pacesetter and was a version of the top-of-the-line Fireflite convertible that stood out even in the glitzy mid-Fifties.
Its body was white with a gold soft top and gold side sweep. The gold anodized trim included special aluminum wheel covers, and the aluminum mesh grille was gold with a silver "V" insert. Upholstery was gold vinyl with brown tweed inserts, carpeting was black with gold "Lurex" flecks, and the steering wheel was white and gold.

Unknown to the public, the real pace cars were fitted with a version of this engine bored to 341 cid and fortified with dual quads, a high-lift camshaft, heavy-duty valve springs, aluminum pistons, forged steel connecting rods, and a forged-steel crankshaft shot peened for strength. This bigger engine in the pace cars produced 320hp.
