I thought I would add some pics of the original 72 Indy Pace car and give a little history behind the Hurst Olds and the 72 Hurst Olds Indy Pace Car.
In 1968, GM had a corporate edict that did not allow the installation of any engine larger than 400 cubic inches in an intermediate body. Thus, the 442 had a 400, the Chevelle a 396 and the GTO a 389. Shifter mogul George Hurst had a '68 442 that he had swapped an Olds 455 into, and found the swap to be not only successful, but relatively simple. Not only was there an increase in power, but the 455 actually weighed less then the 400 it replaced, so the 442's legendary handling remained intact. George's right-hand man, Jack "Doc" Watson, took the idea of the engine swap a few steps further, adding special paint, a Hurst shifter, engine modifications, and a walnut dash applique, and the Hurst/Olds was born.
The first Hurst/Olds was almost a sleeper. Sedate looking in its silver and black paint scheme, it was far from sedate acting with 390 horsepower nestling under the hood. Based on the already potent 442, the H/O featured a special Toronado-only paint color, Peruvian silver, accented with black stripes and a black trunk. The 442's 400 was replaced with a hot-rodded 455 from the Toronado, which featured big-valve heads, lumpy cam, specially modified carb and distributor, and the W30's ram air induction system, with twin scoops under the front bumper. Air conditioned cars lost 10 horsepower, but still, the "gentleman's hot rod" was able to show its taillights to most competitors. A unique feature found on the '68 was the red plastic inner fender liners, which were slipped into the package by Olds boss John Beltz. On the inside, the '68 featured a walnut inlay on the dash panel and a short plastic console that housed the Hurst Dual Gate shifter. Production started on the cars late in the model year, and was handled by Demmer Engineering in Lansing, MI. Demmer had only about 30 days to convert the planned run of 500 cars. Olds had thousands of orders it couldn't fill, and the production run was finally upped to 515 to accomodate a Lansing area Olds dealer who demanded more cars. The '68 was a success by any standard, and would pave the way for a long relationship between Oldsmobile Division and Hurst Performance.
The H/O returned for '69, moving to the opposite end of the spectrum from it's silver older brother. This year, the car went wild with Cameo white paint, Hurst Fire Frost gold stripes and panels, and a monster "mailbox" hood scoop and functional rear wing. The fiberglass hood-mounted scoop provided better airflow than the under-bumper scoops used in '68. Specific 15" chrome wheels with Goodyear Polyglas GT tires put 7 inches of tire to the pavement. Motor Trend magazine dubbed the '69 "The Hairiest Oldsmobile". Mechanically, it shared the '68s drivetrain, except the 380-horse engine was the only engine available. High 13 second times in showroom trim were possible, and slicks and headers could get the car into the 12s. Just about every convenience option that was available on the 442 was available on the H/O, giving the owner a range of equipment and luxury options not generally found on musclecars of the era. Two convertibles and 912 hardtops were built. Fast and flashy, the '69 has the highest profile of all the H/Os.
In 1971, a local Dodge dealer wrecked the Indy 500 pace car coming into the pits after the pace lap. Because of that, manufacturers were reluctant to participate in the Indy pace car program for 1972. Hurst stepped forward with the '72 H/O, and the Hurst/Olds became an Indy pace car for the first time. The '70s were a time of change, and the H/O reflected the times, becoming more luxurious and less powerful. The Cutlass Supreme hardtop or convertible were used for the basic platforms, but a 455 engine was still specified, along with the W25 fiberglass hood and Dual Gate shifter. Cameo white was again the only color choice, but the gold paint was replaced with reflective gold decals that really lit up at night. Hardtop versions came with a unique padded vinyl roof, and a power sunroof was an option. There were even a few Vista Cruiser station wagons made up in pace car trim for use by the medical staff at the track. The '72 is the lowest producion of all H/Os, with 130 convertibles, 499 hardtops, 220 of the hardtops were sunroof-equipped, for a total production run of 629.
Oldsmobile continued to make Hurst editions until 1988 but the performance era of the late 60's and 70's was over. From 1973 on, most of the Hurst/Olds units were detuned and mostly appearance packages.
The following is a pic of the 72 pace car used at Indy the day of the race.
