I have a 2 row Champion rad on my 65 dart & tho a 318 DD does not test it's cooling capabilities but there has been NO leaks & only had to redrill 1 hole on one of the side mounting flanges for it to be a drop in. dont remember if it has flanges to mount a shroud or not but I'm thinking no iirc cuz I had the metal shroud that came on the 65 dart 3 row OE rad in my hand at the time. On the cav plate I traced a round circle on the side of a junk clothes dryer slightly less in diameter than the OD of the vanes with a compass then cut it out with a saber saw & cut a hole in the center then had my welder weld it to the vanes in the center & on the tips of the 8 vanes. On a BB you'd have to cut it in half to fit the halves between the vanes & the pump then weld it. Makes a night & day difference in pump efficiency
