Can you tell us which fans and shroud you are using in these pics? From your later posts, it sounds like you are now happy with your set-up? Like you, I have about 2-3/4" to 3" clearance from the water pump pulley bolts to the radiator core. Champion 3-row so I'm trying to solve the same problem as you before I finish my build. Derale makes a single 17" fan (2400 CFM) and shroud that may be able to be cobbled a bit to work. Thx!
