Bubba, if you choose to go with a aluminum replacement, you could always get the lower outlet changed by a local weld shop. They could weld on any outlet you want or change the one on there. I have seen that done with good success. Mine is a straight lower outlet, but since I run a 250 engine, it was easy for me to adapt. In fact the lower hose runs under and around, then over the top of the oil filter. I picked up about 3/4 of a gallon of coolant just in the hose!
