So you are using this 2.2 fan as a pusher. I also have a 440 in my 67 R/T that, at idle, gets up to 210. i know that is not a danger zone yet, but I have not let it sit for longer and fear w/ summer coming that it will continue to rise. I was told to get an elec. fan as a pusher, my current fan is fixed, 180 tstat, clean recored 4 core orig. radiator, etc. Will the pusher electric help??
My car still runs well at these temps. I fear this Charger has a fuel line, maybe metal, running too close to the block. I would move it or insulate it as my '68 Firebird had this issue and would eventually die until I let it cool for 1/2 hour...
retarding the timing increases heat. I will advance a little more and see what happens and check that the fuel is not lean/// Any other suggestions for both of us. Sorry to partially hijack...
