No idea on the pulley ratio.

Running an 18" 7 blade Mopar fan with the jag clutch.

Tried the 6 vane pump and just because the milodon one with the anticavitation plate.

Running the shroud built for the rad by Wizard cooling.

Fan's halfway into the shroud maybe a bit more.

From reading up on the clutches the Jag clutch only comes in standard duty as per Hayden. Standard mean no hot idle lock up feature so it'll never truly roar when hot.

Running a 180 T-stat and it'll hold that no issues when staying around 30-40mph and up. The clutch just doesn't pull very hard. Fire it up in the driveway it will idle for 20mins plus never gets hot. Go a few blocks and get it up to 180 for a bit and then try and idle and it will start to creep. 205-210 never tried to see how bad it will get.
