I ended up getting the California Pistachio from Whole Foods, so I renamed the cake to "California Pistachio Cake." It didn't seem appropriate to call it Sicilian cake :).
The cake baked about 40 minutes. And it baked flat on top! That sort of never happened to me for butter cakes. I did spend some time making sure the top is smooth and used a silicone spatula to do this (vs. offset spatula). However, it is still amazing to me that it's completely flat. Wish I had taken a picture of it so I have proof, :)).
Next, the buttercream. I have never made the neoclassic buttercream before, so I was naturally curious of the taste. So far my favorite buttercream is the mousseline, which I've made several times. This buttercream is easier to make than the mousseline. It is also easier to work with. I frost the cake with no effort and in very little time (and no my friends, let me assure you it is not because I'm becoming an expert in frosting cakes). Now the part that I love the most is "throwing" the pistachio nuts onto the cake. This is like the easiest decorating that I've ever had to do on a cake, just throw the nuts on it, and make sure that it's evenly covered. And ta-da, the result look pretty!

The cake was a huge hit. I think it's hard to have a cake that uses sour cream taste bad, but it is really really good. The pistachio flavor is pretty faint but I love the crunchy texture of the nuts against the soft moist cake.
Oh forgot to add that I use vanilla paste in the buttercream, I don't know if you can see little black specks in the picture. Also I added a Tbsp. of amaretto to the buttercream (following Matthew, one of Rose's forum blogger) - it added a nice touch to the taste. I still like the mousseline better. But I do look forward to next time when I'll make the neoclassic again - and look forward to piping it!
