Hi, looking for some insight. I have a fresh 350 sbc, gen 1 that is overheating above 210-230. I have a new high-flow pump, all new hoses, new 180 thermostat, and new 3-row aluminum rad. Also note a new flex fan without a clutch. I'm not trying to overthink it, just doesn't make sense. Also ordered a new temp gauge (auto gauge)to ensure temp is accurate.

In my experience a clutch fan cools better. I just went threw this with my K30 and attributed the problem to the fact that I was running pulleys and brackets from a car the truck series pulleys are different diameters to cause the components to spin at different speeds
