Biggest most massive 4 core rad for a 68 Barracuda?

airwoofer said

OK, my fish has a very large but thin radiator. The "puller" elec fan is offset so it clears the water pump pulle (elec motor). Problem is it is about 1/2" too high and the local rad shaop wants over $300 to recore it and shorten it. I think I can buy a Champion cheaper.

Anybody have any experience putting a Champion into a fish? The opening is 22 1/2" wide by 16 1/2" high. I suppose I can mount a "pusher" fan on front of the rad.

And what's wrong with a little glycol in that distilled water? My car gets exposed to freezing over the winter sometimes.

I have a Champion radiator in my 68 Barracuda with 70 up aluminum water pump. You have to use a Jag short fan clutch (forgot the p/n). The top hose was too much toward the center. So my MP fan would not fit. I need a 1" smaller diameter fan than the MP diamter. Also my stock 68 fan shroud will not fit because top hose gets in the way. A 70 up radiator might be better choice.

Even will all that. I ran a 1" small fan and no fan shroud. I've put 2,000 miles since April 1 on my stroker 416 motor without any overheating. I've run it all day at roadcourse 130mph hitting 6,000 rpm no problem. I've run it in 95 degree heat on the freeway cruising 3,800 to 4,000 rpm for 80 mile trip. I've also ran it in stop and go traffic jams too. If it does idle for a really long time in major L.A. gridlock in summer heat it will get warm up to 200deg. A fan shroud will really help in that extreme case.

I also run distilled water, Justice Brother Super Radiator Cooler (reduces temp/cavitation water pump lube), and Justice Brothers Cooling System Protector (anti corrosion/ electrolysis/cavitation, water pump lube).
