Do all A bodies have overheating problems?

Okay. Similar set up. 340 six pack in barracuda. Same problem in traffic. Same timing. Cam 528/528 solid lifter cam. My over heating solution. Griffin 2 core. Two cores are 1.25" wide. Hayden short fan clutch with viscious fan. 5 blade. Aluminum fan shroud. Two 10" electric fans mounted on the front as pushers. I only need to turn the fans on in traffic. Now the fans will not lower the temp in traffic but the temp does not climb. I also have a trans and oil coolers as well. Hope this helps.
