I believe that a stock C4/LT5 with a stock radiator and fans that has no debris in the air flow path will operate in the normal temperature range.

If you make any modifications that increase power, you will have to modify the cooling capability to keep up. Or, as a minimum you will have to ensure that the air flow through the radiator is not reduced by debris.

Certainly true about having a clean radiator, but even with mods I have not had any overheating issues. I have Marc's 510 HP package which includes his chip that modifies cooling so that both fans come on at 205 degrees. When I first bought the car and again when we did the engine, we checked the radiator for debris and found none. In the two years I have had the modifications, including some mighty hot days (not many this year!), I have never seen coolant temperatures in excess of 208 degrees. Early on I added a debris screen just in case. So a clean stock radiator with both fans coming on at 205 seems to provide adequate cooling for mine even for a slightly modified engine. --Bob
