I have a 72 supreme, stock 350, is it a 3 or 4 core? Think I need to replace it what should I go with?

Just replaced the radiator in my 72 supreme. I picked up mine at Summit. I am using their Classic OEM radiator. Fits perfectly in the saddles, trans lines....etc.

What part of the country do you live in? If in the Northern states or Canada the 3 row might be fine. If the Southern states where its hotter in the summer you might want the 4 row. The simplest would be replace whatever you already have. If you presently have a 2 or 3 row and upgrade to the 4 row you'll have to change the brackets at the bottom of the radiator, and get a different top plate. So I'd consider your climate and goals for the car. I tend to overbuild just for the extra margin of safety, but that's just me!

If your not sure what you have right now, look inside the radiator and count how many rows of tubes thick the core is. It could be a 2, 3 or 4 row.

Without A/C, it's a two row. With A/C, it's a three row. I can almost certainly guarantee that you don't have a four row. The core support and top plate for four row radiators are different. Is there any reason why simply replacing with an original style (or better, just having the original recored) is not an option?
