I can't comment on your specific setup but my CR had a history of running hot (both the 347 and 302 engines) in stop and go traffic and outside temps in the 90s. I had a 4 core Modine brass/copper radiator with dual 11" puller fans on it.
The first issue was the plastic thru-core mounting clips wore a hole in the radiator tubes. I will never mount a fan that way again
Nothing touches the core tubes on my car radiators anymore.
Second issue was the smaller dual fans weren't really pulling that much air, especially for the power they were drawing. I even built a nice shroud so they pulled air through the whole core.
I swapped this setup out for a same sized aluminum radiator that is multi-pass. In other words, coolant passes through core 3 times before it exits the radiator. I use the largest Spal fan on this that I recall is 17" or so.
No more heating issues at all. Well, the only heating issue now is that it takes forever for the engine to come up to temp on cool days
The electric fan really only comes on when I'm stopped in traffic or at a long light. I've been in stop-an-go traffic in 105 outside temp and the fan keeps it cool.
Since you've already got a replacement radiator, I'd suggest you mount fan on a shroud instead of on core and use a single large puller fan. The large Spal is slim enough to mount in front of the rack and pinion even when on a shroud.
