No just normal onesAre you running solid motor mounts?
Yeah I pulled off the flex fan and the spacer just so I could mock it up with the new Hayden clutch fan and that looks pretty close. Motor mounts are a few months old. I'm not sure why my engine would be so much closerIf the new one is even closer I'd be concerned. Maybe run poly mounts.
Are you running solid motor mounts?
Because that is close shown above
It would seem so but I don’t know for sure. I’d bet there’s a bit of science behind the use of less blades. One example is the MP Viscous fan package offered for years and years that came with 5 blades oddly spaced apart. All I know about it is, it really moves some air!In regards to mechanical fans. more blades the better?

Oh alright that makes me feel a little better about it then lolThe trans mount is captured and restricts forward motion to less than 1/4 inch.
My son's been driving his car like this for near 10 years, and he's a very spirited driver.

I agree with you that in that one condition the shroud will be fine BUT most of the time the car is moving and for air to turn 90 degrees is not easy. And it WILL build up static pressure between the shroud and the rad and that WIll cause airflow issues at anything other than sitting still.I'm gonna disagree on you on this. The Derale fan shroud stands off the radiator at least an inch creating a plenum that will allow the fan to draw air across the entire radiator
One guy saw a 3.85% gain in HP and 8.93% gain in Torque going from clutched mechanical to electric. Whats a ~4% gain of HP on your motor? 9% torque gain?
So sorry, where is the air turning 90*’s in the radiator system?I agree with you that in that one condition the shroud will be fine BUT most of the time the car is moving and for air to turn 90 degrees is not easy.
In a moving car? I’m having a problem seeing this.And it WILL build up static pressure between the shroud and the rad and that WIll cause airflow issues at anything other than sitting still.
Why? The amount of draw on the alternator is minimal.Agreed, for more improvement, disconnect the field wire to your Alternator.
How much power will a stock 3 core radiator dissipate? Better yet, or easier to understand, how much HP?If an A body can run fine from the factory with a 383 or 440 under the hood with stock parts why recreate the wheel and cross your fingers that the new combination of parts will be good for a mildly worked over 318 or 340 or 360.
. Air in a rad plenum is no different
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.So sorry, where is the air turning 90*’s in the radiator system
If the fan hole in the shroud is smaller than the area of the radiator core there will be an increase in pressure in the shroud. But what I'm talking about is if you put a flat surface in close proximity to the back of the radiator a high pressure zone is created and it will slow the airflow.In a moving car? I’m having a problem seeing this.
It's not the load from the field cir, it's the load that the alternator puts on the engine trying to power all the load of the car.Why? The amount of draw on the alternator is minimal
From what I have seen the stock 383 radiator is physically the same size the inlet and outlet is larger in diameter.Is there a size difference between the small block and big block radiator? I have a stock 3 core unit in the wife’s ‘67 Cuda
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.The Taurus 2 speed fan will pull 12 (165W) and 30-33A (415W). Thats nothing compares to a mechanical fans drag. Ill keep my electric and let the community determine what is best for their application with the data in this thread.
Yeah I might give one a tryThose 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.
OH! Gotcha!!!! Poorly made fan shrouds!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.
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.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.
This is very true.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.
Also giving thought to this move.Yeah I might give one a try
How close is it? Sometimes pictures can be deceiving. What motor and transmission mounts are you running?So check it out guys I got everything installed with the cold case radiator and clutch fan and this is how close it sits. Also got the Taurus fan to take a look at it and see if that would work but tell me if this fan clutch too close for comfort

Stock mounts except I might switch my engine mounts to the mighty mounts soon. You can get your index finger in between the two and that's about it I want to say half inch or soHow close is it? Sometimes pictures can be deceiving. What motor and transmission mounts are you running?
