looking to upgrade to a bigger radiator for WRL endurance racing. 92' Fox that we put an aftermarket (used) 94-95 3 core radiator in. It was full of stop leak so didn't work well. We have a very mild to almost stock 302 carb motor in the car. What's the book say on HP rating for this radiator as an alternative?
There are a lot of variables that can dictate the efficiency of a cooling system. I've personally seen these radiators perform effectively in street cars with well over 400 horsepower. The additional demands from endurance racing may be a different story. I would recommend installing a fox body radiator if your car will still accommodate one. Fox body radiators are larger, therefore higher capacity.
