Champion rad fit / 73 Duster

I’ve been reading thread after thread while searching on FABO about this. I am putting a 360 in soon. I’ve read some “ Champion 3 row fit great”... and I’ve read “ Champion fit only after cutting the rad support, electric fan, bla bla”. My question is simple. Is their 22” 3 row a drop in as they say it is? I really don’t think I need the 3 Row for 350hp max build. Not sure The EC374 will fit. I see it’s a 2 row. Seems that would be easier to fit the clutch and fan in with also. Thanks guys.
