Stock C-Body oil pan, windage tray, HV pump. Check to make sure your steering idler arm does not hit the pan. For some reason some of the C-body oil pans with the notch still hit the pan and may need a small dent. Also make sure you have the clearance for the HV pump. It will be longer than the stock one. May have to shim your motor mounts. For extra oil, use a larger oil filter, I use a Royal Purple
