Is the fixed fan 4 blade?, 5 blade? 7 blade?....if it's a 4 I'd switch to a 5 minimum or 7 FIXED, no clutch...
The blade should reside at least 50 to 75% inside the shroud for maximum pull
No mention if you've flushed the coolant and replaced?...personally I prefer Zerex G-05 with Redline water wetter, I've found the Redline WW good for up to 10 degrees less in my wingcar which runs "very warm" engine wise and underhood temp wise due to the nosecone's small opening... the Zerex is slightly clear in color and doesn't stain like the standard green juice, and Zerex is an IAT not an OAT (orange death Dexcool) coolant, Zerex is about all I run in the DD and toys, if your going to run Zerex, flush the system completely/thoroughly ....

I'm completely in agreement with Mike! I used the Zerex G-05 with WW in my 68 R/T that was a hot runner from the day I started it. I can recall one of the previous owneres talking about how hot it ran. It definitely had positive results. easy first step Bill! Good Luck!!
