new radiator sizes

[mikesacs]

I have a 62 1/2 ton that needs a new radiator. It has a 400 small block automatic. Looking through the parts catalogs I have two choices for the heavy duty (3 core??) with tranny cooler. Either 21 3/4" wide or 23 1/2" wide. My current radiator is the stock 21 3/4" wide and does not have the cooling capacity. My question is - will the 23 1/2" wider radiator also bolt in? I'd rather get the wider one if either radiator will bolt in.

i have a 63 and went with a stock size radiator but i also went 4 core, in az. you need all the help you can get

Always go with as big as you can. You can adjust the total temperature with your thermostat, but you can't solve cooling issues with a tiny radiator

You might have a 6 cyl radiator. A V-8 radiator should bolt right up.

I went ahead and purchased the same width radiator. I was afraid that the mounts and fan schroud would not match up if I went with the wider one.

I agree that the bigger the better, but didn't want to replace teh fan schroud.
