Been here and got the postcards.....
I have a FE that displaces 454 and have NO cooling issues. The solution is not Water Wetter, holes in thermostats, Taurus fans, or anything other than simply moving enough air over the cooling coils to remove the heat.
After 3 different fans/shroud set ups I found that the Lincoln Mark VIII is the largest cfm fan made. It can be had at any Ford dealer. With minor trimming of the shroud it goes right in. I use a 160 degree thermostat and a 180 switch. In 95 degree weather in stopped traffic, it drops the temperature like a hammer. One problem…..It draws a lot of amps….like 45, so a 100 amp alternator is required.
Works for me.
