One other note is the timing set slow, My old carbed 460 will run about 20-30 deg hotter in the summer if the timing is to slow and will get hot at an idle. Thats with a 4 core super duty radiator, and big 8 blade fan. With the timing set at 14-16 deg it never heats up. Just trying to help here, I may be totaly off here.
