I am installing an aluminum radiator on my 68 327/350HP 4-speed to improve cooling for parades, etc. I am putting a radiator designed for the '65 396 big block which should be improved cooling. I m also converting to a twin 11" SPAL electric fan and here's where I need help.
I will leave my sending unit so my temperature guage works. I want to use two thermo switches, one to bring one fan on at 185 and shut it down at 165, the other to kick in at 195 and shut down at 175.
Two questions; 1) where/how can I mount these thermo switches?, and 2) what is the best way to supply power to the fan relays so I don't have to go all the way back to the battery?
Thanks in advance.

It looks like I can install one thermo switch in the top of the intake manifold. Are the heads on the 327 identical? Would there be an opening in the other head that I could use for a thermo switch?
