runnig hot on hot days

[Monster]

Well,
I thought that I would bring this back to the top since I do have an update. Since I had done all of the usual checks (thermostat, coolant, radiator, head gaskets, timing, air flow through the radiator, fan operation) I started thinking about the actual flow presure of the water circulating in the system. I looked into a number of waterpumps and contacted manufacturers. One of which was Brassworks who makes FlowKooler waterpumps, I read an article and these guys appeared to know Ford FE's so I called. I was told that under normal operation (up to 3300 RPM) that their products would help, however if I run at 3000+ I should consider getting an Edelbrock (reference from a competitor, wow). I contacted Edelbrock and sure enough, their waterpump is specially CNC designed and here is information that you don't get from their web but should be there.
In an independant test the "Edelbrock pump generated 11.8 gal/min. more than the leading pump with similar design" and what I find equally important "all other pumps were unequal distribution one brand as much as 2gal./min per side, the Edelbrock was within 1/10 of a gal/min. per side (balanced cooling to both heads)." Plus the Edelblock is the only pump I found designed to run at high RPM. This all explains why my high speed temp dropped about 15-18+ degrees after I installed my new Edelbrock waterpump. (previously @75-80 MPH the temp would rise to 190, today it was @ 170-175 , I pulled off the highway and waited for the temp to rise to 190 (fan switched off) got back on the road and the temp dropped back down to 170 within a minute at 80MPH.


Thanks,
