66 Dart oil pan

I am asking for help yet again. I am one step closer to getting this car on the road but here is my current dilema. It is a 66 Dart that had a Slant 6 in it. I am putting a 318 in there. I ordered the conversion from Year One which allows me to use the /6 K-Member but stuff the 318 in there. I have been told by 1 person at year one that I needed to use a low profile center sump oil pan, which they want $239.00 I then called back and talked to another guy who said the stock pan is fine, but he wasn't 100% sure, so he told me to email tech support. Well still waiting for an email back, but not going to hold my breath. You guys have been great on here, so I am hoping you can help with this. Does anyone know that oil pan can be used?
