The first things I noticed about your cooling are the very thick core of the radiator, I think more than likely it may be contributing to your issue. I don't care for the spiral hoses either, I prefer the molded ones as they don't affect the flow. Double check your belt routing. Your timing can also be an issue from what I've read here. Removing the pusher fan was a good idea, all it does it block air flow. The pullers looked to be marginal also. Going to the Intrepid setup is a step in the right direction, just make sure they're wired correctly and seal to the radiator with a proper shroud. You've sealed up the radiator to the support so that's good. Not knowing how the core was constructed it's hard to say what's going on there, single tube is way better than multiple tubes.
SBC 350 Overheats
I've been battling an overheating issue for quite some time. Now I do understand it is 100+ degrees out right now, but I'd like to believe the engine should still be able to cool itself off.
I've got a big three core aluminum radiator, with dual electric puller fans, and smaller electric pusher fan. Running a 195 thermostat at the moment, was running a 180 (no change). There is ac in the truck, but the overheating problem still exists with the ac off. I am able to open the hood and let it idle and it will cool down to around 210. Doesn't seem to matter if I idle or drive around, if anything heats up faster when driving around.
The trucks radiator appears to keep up for the first 3 or so openings of the thermostat, keeping close to 195. But after than it seems to overpower the radiator, and the fans are just blasting 200 degree heat constantly.
Here are some picture for reference.
