Need cooling system reccomendations/setup - 02/22/15 02:41 PM

Well the BB is about to installed the 72 Cuda. It was originally a SB car so I need some recommendations on radiator, fan etc. It is a -1 headed BB so I think I need something substantial. I plan to run a mechanical water pump but am open to recommendations you have had success with. This a street driven car located in Florida. Thanks in advance!

Without knowing how much HP it makes I would say..
get a big radiator, a good shroud, a good elec fan
and a AC water pump

GOOD SHROUD !
A big radiator loses any benefit if you aren't dragging air through it.
I have seen more than a couple instances of really unfriendly drivers settling down and driving like a normal car would by simply adding a decent shroud to the mix.

I run a generic Summit radiator. The dual fan set-up is out of a new Challenger. It fits easily and the shroud is part of it. These fans MOVE some air. Not a great pic but you can see the upper mounting bracket. The lower bracket is similar.

I am guessing the motor would make around 550-600hp.

Doug like that setup. Can you tell me more about the radiator or have a part number? On the double fan setup...that's lind of what I am looking for is a part I can grab from a parts store do you have the fans on Thermoswitches? Do they come on at the same time or incrementally as temperature rises?

This is my set up on my Rampage street/strip ride
(590 hp)... the fan shroud is from a HHR, comes as
a assembly... I also use a Summit radiator
EDIT
the fan is on a thermo switch that I got from a local
parts store

I have heard a lot of guys singing the praises of the HHR fan set up.
My car has a BIG aluminum radiator and with a single 15 " electric , I thought I would be O.K.
Not even close.
The dimensions of the aluminum radiator are very close to the stock A body radiator , so I bought the HHR fan / shroud combo.
It covers the entire core and I went from creeping over 210 degrees to never going above 190.
If one will fit your deal , it is the best 50 bucks you will ever spend.

I live in the mojave desert and my BB stays pretty cool w/a 26" alum. Griffin radiator, a Moroso drop in w/pump and the HHR Chevy fan which has it`s own shroud built in................

I also run a Summit radiator: http://www.summitracing.com/parts/sum-380428/overview/
This one fits my 22" core-support opening perfectly. I run a Summit flex fan: http://www.summitracing.com/parts/sum-g4917
with a custom made aluminum shroud. My motor is more in the 500 HP level, but it runs cool with no issues. I've thought at times of adding an electric fan, but the current setup cools just fine. I'll see if I can find a picture of the setup.

I just run a toggle switch, thermo-switch would be better. My motor has never been dynoed. Has run 147.8@3340lbs so I'm guessing somewhere around 875hp. Fans came from the scrap yard. Pick your size and outlet location.

If you go with the double fan set up like Doug has
you can have each fan come on separately if you run
2 thermo switches with each set at a different temp..
the thermo switch I bought was about $18 if I recall..
just weld on 2 bosses to the radiator tank with 1/8"
pipe thread.. the switches come with a 1/4" temp
probe that you install with a compression fitting

Cut the inner rad mount for the small radiator out of the car and trim the frame tabs back and stuff a 19x31 in it so it sits flush with the support.... Then fab a cover from the grill to the rad...Never over heat again!

Stock radiator or stock replacement with higher density fin count and 4 row. Or aluminum radiator that is 100% bolt in stock replacement. A stock fan shroud will bolt to that. You can run a 18" fan and hayden HD thermostatic fan clutch (MP Viscous Fan kit is discontinued). Also run a Edelbrock or similar high quality aftermarket water pump.

Hopefully your block was thoroughly cleaned and picked free of debris and sediment.

Since you are in Florida run 25% antifreeze. That cools better than 50%. Or better run distilled water and radiator additive like Justice Brothers Super Cooler #22p or equivalent coolant additive with rust prohibitor and electrolysis resistance.

For 500-600 hp, that will give you consistent cooling performance on the street, easiest excellent sealing fan shroud and radiator to yoke, and not tax your electrical system. Adding high density foam between your radiator and radiator support and between your shroud and radiator to make a perfect seal will help some for little effort.

Okay so basically,

1.) Biggest Radiator you can make fit
2.) Aluminum Radiator preferable
3.) Electric Fan with shroud that covers the most area of the radiator
4.) Good Water Pump

Got it!

I have been looking at the Summit radiators and it seem they are all 2 pass. I know other brands seem to indicate 2,3 and 4 core. Is this not necessary? Also, is it best to run a separate trans cooler rather then one in the radiator?

Thanks!

Core and pass are two different things... core is the
number of tubes (2, 3 or 4 rows of tubes)... pass
is the number of times the coolant passes back and
forth in the radiator(they have walls in the side tanks
to turn the fluid across... I run a separate cooler
but none in the radiator.. that cost goes way up
