Agreed & for your app an alum will be fine. I used a Champion ($189 to my door/eBay) in a 65 dart with an 83 318 & it was perfect tho a 318 sure ain't gonna test its cooling capabilities. it was a 2 row and there's been talk that the coolant tubes are smaller but for your app it'd be a non issue. I only had to redrill (1) mounting hole in the Dr side flat flange. If you get one check that it is flat & all welds are good/complete tho those reported probs are somewhat scarce & reportedly have been addressed. The alum does look horrid & you'd wanna paint it. You will save hundreds going with alum
