A larger/ modified/ higher HP engine HAS to put out more heat, it's a simple matter of thermodynamics. Now, whether the EXISTING cooling system is capable of staying "with" that increase is the big big question.
Due to modification, I've tried to cover all heat related areas during this build, new three core rad, high flow Milodon water pump, heavy duty oil cooler and heavy duty tranny cooler. Specs: 340, x-heads with 520 lift and 3500 stall and 750 holley dp, torker 2 intake, hooker headers, 3.91s in the back. Maybe my car is running at ideal operating temperature for what it is and I'm just over reacting.
