I had a friend build up a fairly stout 400 (not the # match block, which is in storage), but now I have cooling issues. I saw someone post they had a 4 row radiator in their '69, but I can't find any reliable info on whether a 4 row was a factory option in '69. I'm sure my old 3 row is pretty clogged up & perhaps a new 3 row would be adequate...but I'd be interested to know if anyone has a 4 row & if it's a direct replacement, i.e. no butchering the mounts etc.
TIA!
