I recall reading about this topic some time ago with a 350. It can be done without overheating when the car is moving, but I also recall the owner saying the AC fan is barely enough to keep it from overheating at a standstill.

To answer your question I would say it depends. Different engine setups/combos may run different temperatures. Some run cooler and others hotter. I run the stock radiator here in hot humid south Florida without problems but I'm not sure if it will work ok in a 115°F day at Phoenix. What I always say for someone starting a swap is to keep it stock and if you find heating problems then you can always upgrade the radiator as needed.

Depends on many factors but the big one is how much horsepower it's putting out. I run a custom Alum 4 Core, anything less will over heat on Road Course, and I do have a seperate fan switch for hot day city jam traffic (that I can flip on early if I know I'm caught in bumper to bumper creep traffic).

Some have gotten by with the stock radiator, but I am all for overkill in the cooling area. My SBC car runs a 26x19x3" aluminum radiator and a custom mechanical pump and can idle for hours, sit in stop/go traffic for hours, cruise at 80 MPH/3000 rpm for hours, pull a 1000 lb trailer, etc... all without breaking 190 degrees (180 degree thermostat).
With overkill comes the freedom to drive the car anywhere/anytime without needing to worry about current temps or traffic conditions.
