If the Milodon pan you all are talking about is their 8 qt, then be careful which headers you use. TTI and Dougs will fit. There are a couple of others I'm not sure about. But the kicked out oil pan sump will interfere with the headers on the passenger side. The notch required to clear the front passenger side of the sump corner is the lip of the k-frame. But I don't have a pic handy. The Milodon 8 qt. is also a little bit shallower than the Moroso 8 qt., which also has a drain plug in the bottom of the pan (not good) while the Milodon is in the back side.
