My '93 and all others I've seen from that time frame have 4 core units. A 2 core unit won't be enough to keep a stock 6.2 cool much less a higher HP motor. Ideally I would have a 5 core unit made as big as possible to have maximum cooling ability.

Thanks for confirming that. Ordering an OEM rad tomorrow. I will be asking for the 1993 unless anyone here has info on a better year to ask for? Do you think they upgraded the rad in 97 when the cooling system was improved?

If you get a later model alluminum radiator you'll have to replace the lower radiator hose and coolant resevior. I don't know that either one will give a cooling advantage.
Thanks DD, Ill keep it simple for now and get the stock unit so I can get it up and running this week!
Could you tell me the brand/part numbers you used for your Radiator Cooling Fan Clutch and Blade?
Hello,
My FIL came to me for assistance in locating the correct radiator for his 93 C3500. I was his fifth attempt. Autozone, Pep Boys, O'Reilleys - They have creative part numbers for them and it was easy to confuse a 6.2 for the 6.5L. Also the brass one has no engine cooler installed while the newer aluminum unit does.
I had him buy the brass unit and the Autozone guy gave him a big discount to not come back.
His original lasted 19 years.
As for changing your system to 94 and newer - you have more parts you would need to purchase to make that work. the pressure cap would be mounted on the surge tank, newer updated hoses, etc. A lot of work.
The best you could do is as Jim B mentioned - a custom built unit that sheds the heat.
