Clutch fan vs derale single 2400cfm fan

Anywhere other than where the hole in the shroud for the fan is. The air comes in and through the radiator core fins, then it has to turn 90 deg to find the hole in the shroud ( poorly made flat shroud) to exit.
OH! Gotcha!!!! Poorly made fan shrouds!

From what I have seen the stock 383 radiator is physically the same size the inlet and outlet is larger in diameter.

I am sure the fins per inch and the construction of the tubes is different, not to mention the water pump, pulleys, etc.

I have a stock HP/AC radiator and a stock standard cooling rad. The tubes are the same except the HP/AC rad the tubes are (just numbers for example) 1/2" long by 3/16" wide vs 1/2" long by 1/8" wide.

All I'm going to say about the subject. If you think I'm full of **** so be it. I know what has worked and what hasen't in my life experience.
It’s not that I think your full of it though I thought I was about to strongly disagree on a point or two. But clarification is what I was after. Thanks for clearing that up. Now it makes sense to me. Hence why I asked.
Also thanks for the radiator description.
Much appreciated.

Those Taurus fans are beasts! I've got one I'll likely use on the 66 BB Dart. The T-bird and Mark VIII fans blow a TON of air too. You can't beat OEM fans for electric, as far as I'm concerned. There're lots of good ones out there.
This is very true.
