Recommendation for a good radiator, electric fan and shroud

I need to get a cooling system for my 67. I don't have anything right now so I need to get a radiator, electric fans, fan shroud, can controller, and water pump. I have asked for recommendations in the past and have heard of some radiators people have had good luck with and some of the popular electric fans. But I have also read that the package has to be right for the system to work. Meaning the shroud must fit the fan and the radiator correctly to cool sufficiently.

So I am now asking if someone can recommend a complete system (radiator, fan(s), and shroud). I am running a manual transmission and hope to add AC in the future.

I know that a mechanical fan would work fine but I want to use electric fans if the cost is not substantially more.

I am not going for a stock look. My car will be driven on the road as well as at the drag strip so I want to get something that will cool a 500hp 400 small block on the street and on the track.

I would really appreciate any advice on a good complete setup.

Re: Recommendation for a good radiator, electric fan and shroud

I have been having cooling issues for awhile now on my 69 Camaro. I purchased a radiator and fan from Alumitech. I got the bigblock alumi radiator and the single 16" Spal fan and the Spal digital fan controller. I had them weld in a bung fitting (at no extra cost) in the driver side radiator tank for the temp sensor of the controller. I live in the south and have Vintage A/C on the car and have had no cooling issues since. It was a little more money than I wanted to spend but the cheap routes I went just didn't keep it cool. I am happy with it now!

Re: Recommendation for a good radiator, electric fan and shroud

If you read back thru older posts and by those who have been around 1sty gens for a very long time, the general consenis is stick with stock.
It is not neccaasry true that just because something is marked GM or happens to be 40 yrs old it is faulty design.....when it comes to the cooling system....GM nailed it 100% spot on and more 40 yrs ago...and decraded since then because of competitive cost.

Go stock, save the headaches.

Re: Recommendation for a good radiator, electric fan and shroud

Even if you don't care about the stock look - I think the stock set up for fan and shroud with an Alumitech 23 inch 67/68 Air conditioning radiator is hard to beat. You will want to get a shroud for the 67/68 AC Camaro to go with it, and the total will be less than you spend on an electric fan set up, even getting a NOS shroud from GM. Do a search and you will find more than one person who has this set up with no cooling problems at all well into the triple digit temperatures with healthy engines. The 450hp 400 SBC does fine with this set up never getting above 190 idling or cruising with upper 90's for the outside temp.

Re: Recommendation for a good radiator, electric fan and shroud

I'm using a 93 Taurus 3.8l fan. Comes with shroud and fan. It's a 2speed fan but I only use the high side. It's not loud and pulls a ton of air. This fan will literally suck your hand to the front of the radiator. The only down fall is that the fan draws 35+\- amps. Requires 8 gauge wire and a continuous duty solenoid. I use the controller to turn on my solenoid. Fan is around $125 at napa and has a lifetime warranty. There is a guy on eBay that sells them used for $85

So I am now asking if someone can recommend a complete system .....

Don't forget to upgrade your wiring to handle the increased amp load and budget a new higher output alternator.

Other than that, pray it cools as well as a factory system for 2 maybe 3 times the money.

Now think about that...the alternator has to produce the power to run, which gets/drags from the engine....is there really any advantage and having to upgrade wiring, fit sensors and stuff?

Answered in many old posts and this one many times , and note who suggests ..stock factory...they guys who have been around a long time, worked on many projects, and have got past the marketing propaganda BS...

Re: Recommendation for a good radiator, electric fan and shroud

I replaced my perfectly operating clutch fan system with a set of Windstar fans. Fit real good, only one of the fans turns on most of the time. Motor feels a little peppier around town too. I like the faster warm ups as well.

Thats determined by the thermostat...not the radiator..the thermostat keeps thr hot water back in the engine.

Ambiant temps mean squat to a cooling system that is in good condition (no blocked cores) A stock system will run an engine at 120 /125 deg in 95/ 100 deg ambiant temps.
And a sb Chev should have at least a 180 deg thermostat.

Really? So 100 degree air cools as good as 50 degree air.

So if the water in the radiator is running hotter b/c a fan isnt pulling air through it, the engine wont reach its operating temp faster? In other words, the clutch fan's typical cold-start full engagement which cools the water being sent to the motor will not make a difference in how fast she'll warm-up?

I'm thinking warmer water (coolant) going to the engine will warm it up faster - just me.

Re: Recommendation for a good radiator, electric fan and shroud

the hot water will only get to the radiator to be cooled there if/when the thermostat opens. The thermostat does determine warm up time assuming the block and coolant in the block is the same in your comparison at the start.
