where are all of the high HP 180 pump trucks at?

I was looking through the 12v dyno numbers and I noticed that most of the 600+ numbers have been made with the retard timing 215 pumps. I did not see many 180 pumps making the same power. I have heard the 180 are a better plunger design, and many say they "feel like they fuel harder." Just looking into the 180 pump a little.
