Hey guys, my chevelle I bought didn't have the correct radiator in it when I got it.It was pretty rusty looking inside so I thought I would just replace it.It looks to be a 4 core.The one I bought was for a 66 chevelle 396 and when I took it out of the box it looks like it is a 3 core.Do I really need a 4 core or do you think the new 3 core will be fine ?
Thanks
