Sorry it's radiators again

I guess I could also tell you what doesn't work. Here is a list of parts I originally put on the car that just could not keep up under any circumstances.

The above listed rad in the stock slanty opening,the shroud, the core-seal, the hoses, the 7-qt pan. the 7 blade all steel fan with a brand new viscous clutch, a 160* stat, and water.
It worked at about 45 mph.
It was no better with a big flex fan, actually worse, now I was down to 30/35 mph.

Things took a turn for the better when the hi-flo pump went on. And with the Ford T-clutch it was all over.
So Ima gonna say The anti cav plate and the 7 blader are must haves.Probably followed by enlarging the rad opening.
Sucking hot under-hood air (I have TTIs and Alumunum heads), I had trouble with consistent idle quality, so in about 2006,(I'm guessing), I cut a hole in my hood, and since that day my idle and low-speed problems have been over. I mounted an oval air filter house directly sealed to the top of the hood. Then I sealed the Carb to the bottom of the hood. When I open the hood you can see directly into the venturies. I think my power doubled that day!,lol
