For its 15th Anniversary Edition, the '83 H/O came only in black with silver rocker panels. Chrome 15" wheels fitted Goodyear Eagle GT tires, and a power bulge hood and rear spoiler gave the car a purposeful look. A modified version of Oldsmobile's 307 CID V8 was installed, along with 3.73 gears and Hurst's radical Lightning Rods shifter. Dual exhausts with rumbling mufflers meant there was no mistaking the H/O for a garden variety Cutlass. A new style "Hurst/Olds" emblem was introduced, and red and silver stripes separated the black and silver paint. Demand for the car was very strong. Originally, 2500 units were scheduled to be produced, but Olds had to up that number to 3001 because of high demand. That may have been a factor in bringing the H/O back for '84. The paint scheme was reversed, with silver being the main body color, and black on the rocker panels. In most respects, the '84 was mechanically identical to the '83. The '84 did get a stronger 8.5" rear end. 3500 units were produced in 1984.
