LT1 Be Cool Radiator

Is there another (cheaper) solution for a radiator for a LT1 in a 90' YJ? I was looking at the "Be Cool" radiator on Quadratec's website ($869.99). Any other suggestions would be appreciated. I am going to run a 740R4/NP231C setup with the LT1.

This is the link to the "Be Cool" setup

Thanks,
Chris

$869.99 is bloody ridiculous

This is a great thread if you are thinking about a swap. He did a TJ but it is very good.

One of these days I'm going to get a TIG so I can get filthy rich welding a couple tabs to the side of a universal dirt track radiator and sell them as a conversion radiator for twice what they are worth.

Seriously, get a $200 Chevy universal 22x19 aluminum radiator from Summit or Jeg's and make your own mounts with scrap steel. It's very simple. Here is my radiator with Taurus fan. I have about $300 in my entire cooling system including radiator hoses and wiring for the fan.

I wheel it like I stole it and it has never gotten over 210 with this setup.

I had the same Radiator in my last rig only I mounted it in the rear , never got hot unless I forgot to turn on the fan I was running a 350 as well.

That's why I porpusely left the switch out of the fan circuit! I let the ECM decide when the fan is on and off! I go around deep water/mud anyway, that stuff does too much damage.

Until recently I had an Extreme Radiator heavy duty conversion with the stock jeep shroud and fan run off the water pump. It was marginal in cooling. If I let it idle for very long the temp would creep up and if I went over 70 MPH the temp would creep up. One of the mounts on the radiator (epoxied to the tanks) failed. I decided to get a Be-Cool radiator because I have used them in the past with good luck. I bought the radiator from Summit Racing, I thing their pricing is better. I bought the version without the trans cooler built in, and then I bought a Hayden cooler for the trans. I am now using an electric fan from Summit too. The cooling is far better now. I have not been able to get the temp over 200*. I am running this with a 350 TBI and 700R4.

Could it be because you now have the trans cooler seperate like it should be? My dad has an 86 S10 backhalfed with a narrowed 9" and 18" slicks powered by a hot (no pun intended) SBC roller motor. We chased an overheating issue all over and finally out of a guess one day I bypassed the trans cooler in his radiator and the temp dropped 15 degrees! He now has the same B&M fan-cooler I have in the bed of the truck.

I never understood the reason behind combining the two coolers. Automatic transmissions operate at a much lower temperature range (160-180) than an engine does (190-21) so in effect you are actually heating your trans if it is connected to the radiator. Not to mention the mess that follows if the unit fails and oil mixes with coolant.

The previous radiator had the trans cooler in the bottom tank. I have checked the temperature of the trans lines and the supply was at 175* and the return was at 170*. I think that means I was getting some cooling from it but I think the trans should be cooler than that. One of these days I will check the trans cooler to see how it is doing now. The big reason I got away from the other manufacturer is because the mounting bracket failed. The new one is all welded aluminum, I don't think it will come apart. I suspect this radiator may be more inefficient because the electric fan pulls less air then the mechanical fan did at idle but the temperatures are about 15* cooler. The difference is more under load.
