I have a 1970 Cutlass Supreme SX (at least I think I do). I was the second owner, acquiring the car when it was about 9 years old. I came across a website - www.sx455.com -- which has spotter tips. All the tips match up, except I am not sure of the engine in the car. I know it's two barrel. It has the numbers 396021 stamped on it (I do NOT see the F or F1 following the numbers though, which www.sx455 say should). There is also, however, a paper decal just before the radiator. The paper decal talks about it being 350 C.I.D. (and not 455).

Can anyone help me with my confusion and how to tell for sure what engine is in the car?

Thanks.
