How to be cool?

[cyberstang5.0]

I have a 2 core hi-effecency radiator in my pony now. When I had my stock motor, the temp never went above the 3rd line from the bottom durring Houston's summer in traffic. It cooled it so good, that I litterally didn't have heat in the winter time (my motor never got that hot). I have a Black Majic Electic fan too. So you can see, it cooled my motor really good.

Now that I have a big bad 347 , it's not doing it job as good as it use to. Mostly because my new motor runs hotter. Does anybody know of a radiator that I can get to cool it better?

I was thinking about the "Be Cool" radiator that summit has (Part number BCI-82165) but that's a lot of money for a radiator. I am thinking a 3 core alunium radiator will do the trick.
