Default Overheating 427/390

I have a 1968 that I installed a Vintage Air A/C system. Now my car tends to overheat (of course) I'm looking for a 7 blade fan to solve this problem. I can't find one at any of the catalog stores- Ecklers, ZIP, Volunteer, Doc Rebuild and a couple of others. I need help in finding one also I could use suggestions to stop the overheating

Sounds like the system was marginal to begin with.
How's the fan clutch? A slipping clutch may cause overheating when idling or low speeds.

All the fan shroud pieces in place? All seals around the radiator and shroud OK?

If all the parts are in place and in good working order it may be your radiator. Either find a good quality replacement or look into a DeWitts unit?

DeWitts unit? I've just ordered a replacement fan clutch. Radiator was new this year. I'll re-check the seals though. Thanks

I was referring to an aluminum radiator.
If you just replaced the radiator, should be OK.

Are all belts in place? I think there should be two on the water pump though I can't be sure of your year.
