[400reasons]

Hey guys,
I actually read every post in that "Chalk one up..." thread because I am having the same problems. Idles at 180* but when I'm on the freeway with the AC on it climbs to 225-230. My first question is is there supposed to be a spring in the UPPER rad hose? I have one in the lower one for sure. Does the upper hose suck or blow? It is a prefab hose that I got from Autozone and it is pretty squishy. I do have a recovery system. 13# rad cap. '69 bird, with a '71 400 11 bolt pump. I haven't gone there yet, I want to eliminate all the easy stuff first.
Thanks.
