Car Above: SX455 Member David Menke of Rockford. MI - 1970 Cutlass SX L-33
As of May 17, 2021 there are 771 cars in the Cutlass SX Registry
!
In 1970 and 1971 Oldsmobile introduced a new Cutlass Supreme options called the SX Performance Package. The Y-79 code featured several 455ci engine options, 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. Order the right engine options and you had a Olds 442 in disguise. The Cutlass SX was designed to have muscle car enthusiasts avoid the high muscle car insurance premiums. To accomplish these feat, Oldsmobile did not offer different VINs for the standard Cutlass Supremes and the Cutlass SX. Threfore, you cannot ID are real Cutlass SX by the VIN. 

Since 2005, The SX455 Club has been the official resource for all things Oldsmobile Cutlass SX. Bob Peters and a group of dedicated Cutlass SX enthusiasts and gurus have documented all things related to the Cutlass SX and has secured that information on this web site. This includes information on how to identify a real Cutlass SX, every magazine article published, official factory and dealer documents, options codes and color combinations and so much more. No other Oldsmobile web site contains the amount of content for one particular model.
