First things first.
When planning your performance vehicle, remember that you’re building it to
drive, not to sit and steam. Plan adequate space for the cooling system including
the radiator, fan, shroud, over flow tank and mounting brackets. Talk with a
cooling specialist to help you size the system for your vehicle, engine and driving
habits. Consider the investment compared to the total cost of the car.
