68 Barracuda 440 getting hot in traffic

I actually bought the car with the 26" radiator in it and no they didn't cut up the support to make the opening larger. That was another thing I was wandering if I should go with a different radiator because I'm not going to cut the support to make use of it.

Your choice alone! If you want to keep it then you have to decide. Finding a 3 core 22” can be tuff and may be costly but they are out there.
