Pusher Fan Advice?

[1] Post #8 is completely wrong about coolant not spending enough time in the rad. Old wives tale. See link below for tips. Think about this: if the coolant spends more time in the rad, it then means the coolant stays longer in the engine...& picks up additional heat...which the rad now has to cool.
[2] If you have an overheat problem, changing the t/stat rating will not fix it.
[3] Overdrive the w/pump by 10-30% & make sure the impeller blade gap is tight.
[4] The hole in the housing under the stat. You can reduce to about 3/8" diam; it will help cooling because less hot coolant is diverted to the intake side of the pump.
[6] Ignition timiiiiiiiiiiiiiiiiiiiiiiiiiing!!! Make sure you have plenty at idle & 45-60* at cruise. Not enough timing, a sure fire way to cause o'heating.
[7] lean mixture at cruise can also cause hot running, but would have to be veeeery lean....
