A body radiator

I have a 1966 barracuda with the slant 6 it now have the 273 would it still work if so how much I live in california

Check the upper and lower outlets. I think that the v-8 and slant 6 radiators had them in different positions. I can't remember which ones were different off the top of my head. I may be wrong, but I think that there was a difference.
