1974 Oldsmobile Hurst/Olds W-30 455
The 1974 Hurst/Olds was a collaboration, not a decal package applied entirely on the Oldsmobile line. Cutlass S coupes were assembled in Lansing and trucked to Hurst Performance Research in Ferndale, where the production cars received the simulated roll-bar roof treatment, gold graphics, Hurst/Olds emblems, hood ornament, and, on W-30 cars, the Dual-Gate shifter and console emblem.
Two engine paths were offered. The regular 350 accounted for 1,420 production coupes; the W-30 configuration paired a V-code 455 with a heavy-duty Turbo Hydra-Matic 400 and accounted for 380. The 455 was rated at 230 SAE net horsepower and 370 lb-ft of torque. It used KA heads, a Rochester Quadrajet, dual-snorkel air cleaner, dual exhaust, and an OX-tag TH400. Air-conditioned cars used a 3.23 axle, while non-air-conditioned cars used a 3.42 Anti-Spin axle.
FE2 Rallye suspension, front and rear stabilizer bars, power front disc brakes, 15-inch gold Super Stock III wheels, and the Hurst Dual-Gate made the W-30 more than a visual special. Inside, every reviewed W-30 path used swivel bucket seats and a console; black and white interiors had gray cloth inserts, and a Hurst digital tachometer was optional.
The pace-car connection requires careful wording. Production coupes used contrasting vinyl and stainless trim to simulate the roll bar on the roof-cut actual pace cars. Full Indianapolis lettering was optional. A production car without the decal kit can still be authentic, while an ordinary Cutlass with pace decals is not automatically a Hurst/Olds.
Authentication starts with paperwork and then reconciles the body tag, V-code VIN, engine and transmission VIN stamps, casting and part numbers, axle, roof conversion, paint, interior, and Hurst-installed details. The Hurst/Olds Club documents 1,800 regular-production coupes, 380 with the W-30 455, plus separately scoped Indy support vehicles.
