For me The Shining (original) has great atmosphere. I also really liked The Devil's Rejects because when I walked out of the theatre after watching it I felt almost dirty.

I also love the original Dracula for atmosphere, it was all about atmosphere back then. I think Night of the Living Dead (original) was a good one for this too....actually, I find a lot of the original black and whites had more atmosphere, they had to rely on it more than shock and gore.

Not so horror, but had lots of atmosphere for me was Requiem for a Dream...and Pi...but I love darren aronofsky so it could just be me.
