Hey guys, I have a 84 351W thats punched 30 over In my fox. It's got Trick Flow TW's, a new stock replacement water pump, 160 thermostat, 2 core aluminum griffin radiator with 1 inch cores. I've got a flex fan with the proper spacer and no clutch. I've purged the system several times, and I cant keep this thing under 200 for more than 15 mintues. I'm using Dexcool, or whatever the orange type of coolant is called. I have the lines hooked up correctly, and the head gaskets were installed properly. I've gone through the whole list for the most part, and it's still getting hotter than I'd like.I've eliminated the lines to the heater core also. Does anyone have any suggestions.

Are you using a fan shroud? And did you make sure your head gaskets were put on properly? There is a front and a back to Fords, you mix it up and you'll severely restrict the cooling ability to the heads. And why are you using GM coolant in a Ford?

Are you maxed out cylinder bore wise i.e. (has it been punched out before without your knowledge?)

I have a high flow water pump, alum. 3 core rad. and dual electric fans. My fans run off a manual switch inside car. With 100 degree temps i dont have to run fan all the time. The high flow pump might help but i'm sure the dual elect. fans will probably fix problem. BTW i have a 351 .030 over also.

The head gaskets were insalled properly, and this is the first time the motor was bored.
And I was told to use Dex Cool with an aluminum radiator.

Dex cool is only suppose to be used by GM vehicles with plactic intake manifolds and rubber gaskets. It has a lower PH and will no corrode the gaskets. Thats why they URGE you not to put in the green stuff because it will eat away at your gaskets. It has nothing to do with the fact that it has an alum rad.
