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 or more commonly called The Cutlass SX. The car featured a 455ci engine, a 400 Turbo Hydra-matic transmission, a cutout rear bumper with dual exhaust, special SX badges on the fenders and other goodies not found on a standard Cutlass Supreme. It was a 442 in disguise!
In 1970 there were three 455ci engine options for the Cutlass SX. In 1971 there was only one Cutlass SX engine. 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. Finding or seeing a Cutlass SX is rare.
ALL 1970 and 1971 standard Cutlass Supremes and the Cutlass SX models had same basic VIN codes, so identifying a real Cutlass SX can be difficult. This website will help you identify a real Cutlass SX. SX455 Club Members have access to Spotter Tips, Tech & Spec Data, and other helpful, informative and entertaining information.
|If you are thinking about purchasing a Cutlass SX,
do your research before you make an offer.
The Cutlass SX is certainly a unique and rare General Motors muscle car, and will continue to gain in popularity and value as more collector car enthusiasts discover these great cars. Sophisticated styling, luxury options and big block performance make the Cutlass SX a great gentleman's muscle car. Thanks for visiting our club web site.
