Most muscle car experts will agree that Oldsmobile reached its pinnacle in 1970, the same year Oldsmobile introduced a notchback intermediate called the Cutlass Supreme.
In 1970 and 1971 this new Oldsmobile was available with a special option called the Y79 Performance Package and the car was named the Cutlass Supreme SX. The Cutlass SX featured several 455ci engine option, a 400 Turbo Hydra-matic transmission, a cut out rear bumper with dual exhaust, special SX badges on the fenders and other goodies not found on a standard Cutlass Supreme.
Ultra Motorsports is pleased to offer the true GENTLEMAN’S MUSCLE CAR. In 1970 there were three 455ci engine options for the Cutlass SX. In 1971 there was only one Cutlass SX engine option. These engines offered up to 365HP and 510lbs of torque!
The production numbers for this two-year-only (1970 & 1971) model are less than half of the highly collectable Oldsmobile 442 models, plus many of the Cutlass SX cars were sent to the junk yard crusher before the car became collectable. The Olds Cutlass SX is truly a very rare GM muscle car!
ALL 1970 and 1971 Cutlass Supremes had the same basic VIN codes, so identifying a real Cutlass SX can be difficult. The Cutlass SX cars are valued at 20-25 percent more than a regular Cutlass Supreme model. SX455.com provides Spotter Tips and Tech & Spec data needed to identify a real Cutlass SX.
The Cutlass SX is certainly THE “undiscovered” General Motors muscle car, and will continue to gain in popularity and value as more collector car enthusiasts discover these cars. Sophisticated styling, luxury options and big block performance make the Cutlass SX a great gentleman’s muscle car.
