Vehicle running warm 360 la

I looked back through my records/receipts/photos to see what I have on the '69. I used a Hayden #2947 clutch with a 5-blade fan from (I believe) an '85 Gran Fury AHB. The engine has the '70-up accessory drives/water pump, with little clearance to the matching-year eBay-sian 22" molded-tank aluminum radiator. The Hayden clutch is both HD and low profile. It includes an adapter to fit the Mopar pump pilot, which required some trimming to make it sit flush (side of the bench-grinder wheel for a couple of seconds). There is no fan shroud.
I have less than 5/8" clearance between the clutch fins and the core, but as mentioned in a previous post, it stays nailed @ 180°.
