My theory is the stock radiator in our cars is designed to effectively cool our relatively stock engines adequately. When upping horsepower we of course increase the heat. I am thinking our stock radiators can't hack it. to add to that I read on here the stock water pumps suck.. Is the only answer to keep things cool a $400 radiator? I was hoping there was a less expensive radiator out there that can keep up with the increased btu's
 
If your radiator is stock you may also want to think about a replacement radiator. A lot of guys are making good power on the stock radiator. Me on the other hand I am stressing my stock radiator with the A/C on and a relatively stock combo.
 
You have to remember that these things are 10+ years old and the systems dont function as efficiently as they once did.

Some guys get away with the stock replacement radiators, even on big strokers, while some near stock guys need a large alum radiator (for daily driving).

I hadnt heard that the stock water pump was insufficient - I thought they did pretty well. I did decide on a Stewart Stg 1 for a replacement however (partially because the Ford pump was backordered).

Were it me, I'd go aftermarket aluminum (as mentioned) if replacing the radiator. You can save some cash if you do some fabbing yourself.

Good luck.
