I have had a lot of experience the last few years dealing with small block oiling systems with my Super Stock car. There are a few just basic things to look for with a bracket engine. Mostly whichever cam you decide to go with put the cam in the block and remove a oil galley plug from the lifter galley. At full lift make sure the lifter doesn't uncover the lifter galley oil passage where you would end up bleeding off excessive oil pressure. If the lifter uncovers the oil galley you will need to bush the lifters or tube the oil galley. Other than that there are multiple things you can do but unless it's a 8500 rpm engine, a good oil pump, and oil pan will be the best things to do.
