I, personally, am not a fan of chrome PS Pumps. I prefer a nice black pump. when you have a chrome part under your hood, you must keep it cleaned and polished. A dirty Chrome part is worse than a dirty black/stock part. I think too much chrome in an engine compartment is blinding. But that's just me.
I did a quick search on the interwebs and found this engine. this is about as flashy of a motor as I like and it has a black pump on it.
Others will disagree with me. Some folks love chrome and say the more the merrier.
