I put a Milodon 7 quart on my 73 and one from Summit on my 76. Both cars are L-82 with PS and headers with no issues. You need to change pick-up so get the one recommended by pan supplier. I also recommend you get one piece Felpro gasket. Makes installation much easier.
If you run a high volume oil pump, having 7 quart oil pan helps make certain you don't starve pump for oil.

I have a Moroso 7-qt on my 383, no clearance problems anywhere. Well, maybe I shouldn't say that. With a kick-out pan and headers, getting the oil filter in and out is harder than stock, but not that bad.
