At 5 lb that reduces my timing to 16d, safe for a blower motor. I think your stock rad does not have enough capacity to cool your motor. The blower in my case (B&M 142) does require more power to turn and does produce heat.
I don't think break in will help too much. I also have a 2500 cfm electric fan which rarely comes on, only in very slow traffic. Best of luck, you'll love the boost!

Sounds very similar to what I'm running. Running cooler now. I used the stock radiator with the last blower motor I had in it with no problems.
Thanks
