69 under construction / 440

I DONT KNPOW HOW MUCH H.P. UR PUTTING IN THE ENGINE , AND I DIDN`T READ THE POST CLOSELY, BUT I SEE AN OVERHEATING PROBLEM COMING UP ---excuse caps
The 440 is going to be somewhere in area of 500- 540 hp , the rad I have is meant for the big block so I'm confident it should be ok . If I remember right it's a 3 core with dual electric fans.
