A questions for Mike Mileski, did the advice of Marlan Davis at Hot Rod Magazine cure your low-speed overheating issues? I ask because I had a 350 Chevy powered 1970 240Z back in the day. It always ran hot as well. My biggest issue was fuel percolation in the carb float bowls. I have toyed with the idea of making a second V8 Z with an LS3, thinking fuel injection would do away with the heat issues I have in Denver's cooler weather but thinner air compared to Tucson. Looks like I could end up in the same boat as then if guys like you are having issues with modern radiators and engines.
