Fuel Fluke

OK.... My problem is 80% heat related. I drove to the cruise in staying on the interstate most of the time and the temperature got up to 210*... it started vapor locking when I got into the parking lot of McDonald's. I don't have big enough radiator.. all I have is a stock mopar 2 core radiator. I was talking to a mopar guy and he said that he has a small block 4 core aluminum radiator that he said should take care of the problem. He said if it doesn't work that I could bring it back to him and get my money back. My motor is just getting to hot and causing vapor lock I honestly think. I will install the electric fan in front of the radiator and if room allows install the mechanical fan back on. I really don't what to do with the fans yet because I don't know the actual thickness of the radiator.

I think today summed up what I have been battling and that is heat. I'm still going to install a new tank and make sure everything is 100% back there.

So.... what you guys think about the plan?
