Running a 350 small block chevy, bored .60,flattop pistons, solid race cam.
Runs 8-10 laps at 190 fine anything after that gets hot real quick, about 250.
Spray water in the radiator cools off fast.

What does your cooling system consist of? Thermostat or restrictor? Underdrive pulleys? What type water pump? Got a fan shroud? What kind of fan? Clearance between fan and shroud? Need more info.

You need to run 1 to 1 pulleys, no thermostat or restrictor. Very well built fan shroud and a good air supply from the front. Make some kind of a shaker screen to keep mud out of radiator.
