David, thanks for checking in your box of parts, I think I have a line on a Mustang pulley locally that is 5.5" in diameter, still trying to confirm the belt backspacing. I also have a larger crank pulley (7") that I can use. So between those two I will have nearly a 25% differential. David, if this pulley doesn't pan out I'll let you know. On this issue of revving the engine, I don't see any noticeable difference when I do that. So while the pulley change may help, I am not counting on it exclusively.

If I get it up to say 100*C and kill it but leave the electric fan running for a couple minutes, the temp gauge climbs on up to 110C. But I can then start it again and immediately the pump exchanges the radiator and block water and it immediately drops like a rock by 10-15 degrees. Then I kill it again, wait with the fan on for a coulpe more minutes, start it again and I can get it from on down to 85C, all in less than 4-5 minutes doing this. To me this suggests that the radiator is capable of cooling, either it doesn't have the volume or the time to do so. EDIT>> or the airflow is still too low.
