Here are the oil pans I tried. The black one is the one from Mancini. It seems to work the best. They call it a Hemi pan but I think a better description would be a deep 187 pan. It basically looks like the 187 pan but is just deeper. The orange pan is a factory 187, the green pan is another Hemi pan from Mancini and the gold pan is the Milodon road race.
