I have a 1967 GTO,1971 455, Ram Air IV Comp Cam, SD Performance #96 Iron heads flowing at 270 plus, RPM intake to match, Mezeire Heavy Duty electric water pump, Aluminum X-flow radiator, non A/C core support, 1995 Thunderbird 18.5" electric fan run with a continuous solenoid, 160 deg. high flow Milodon thermostat, 185 degree Spal contoller in a welded coupling at the inlet of radiator, all in front of a TH400.
Here is the problem! In 70 deg. weather it is not cooling with this setup! Down the highway at 2800 to 3000 RPM it will creep to 210 deg.
I removed the thermostat and now I can hold it to 195 on the highway, but it is still only 70 deg. ambient temperature. I have yet to try reducing the flow from the Mezeire at this point.
Anybody else who is running this combo, I would like to know how many fins per inch your aluminum radiator has.
I have Pontiac friends here in the club that are running virtually the same thing and are not fighting what I am, and there cars are 11 second street cars!!
I feel the fans should not even be coming on at cruising speeds due to the air that is already being forced through the front of the car.
This was inspired by an article called "Cool Winds" in one of the Pontiac magazines where they used Floyd Hands 66 Tempest for a test car.

Thanks for your help!!!
