Thanks for the update. I too wanted to share my own findings:
Replaced my dual core CFS with a stock radiator, but upgraded to the Camaro SS fan. Knock on wood, itís been 4 months and no leaks!
Now, running down the road, my 5.3 gen V would get to about 197 with the aluminum radiator. Now, with the stock rad it runs about 208, but as soon as the fan comes on, it cools down in a hurry! It has so much more power. I hammered on it pretty hard off road and pulling a boat, and it never went past the 215 fan set point.
