I have a 1969 cutlass S convertible. Some of the parts websites i have visited have not had the cutlass S as an option. All the options they have is a cutlass or a supreme. So, i am under the impression that the cutlass S and the supreme have the same engine from some stuff i have been reading, but i don't know for sure. so any help would be great, and if the engine is the same, then what is the difference? also, i have a a 350 with a four barrel carb if that helps. Thanks!!! might be coming here a lot while restoring this bad *** car.

The '69 'S' and Supreme were different in trim but not too much. Typically the F-85 was bare bones, the Cutlass was a step up, the Cutlass 'S' was another step and the Supreme was top of the line. The supreme came standard with the 350 h.c. 4 bbl Rocket engine but that engine could be ordered on any other Cutlass also. The interior seating and trim on the Supreme are unique to that model.
