Have to admit, this is my first 440. All BBs I've done before were 383s, never a cooling problem.
69 model 440, in my 64 SF. Engine is only .020 oversize. The block was completely cleaned, of course, as much in the water jacket as possible, and flushed out a handful of times.
Radiator is a Mopar 22" 3-core out of a 67 Coronet RT 440 w/ac car. It has the mounts for the two piece (upper/lower) fan shroud, that's mounted up. Fan is a stock 7-blade steel, no spacer, and sits halfway into the shroud. 16 lb. Stant cap. Stock water pump.
I had the radiator boiled out. Out of six listed radiator shops in the area, every one had shut down, years ago, except one...he charged me $300. Don't know what the going rate is, these days.
Thermostats (lol), tried three different ones, all 180, last one a Stant. All acted the same. Once up to temp, it would keep going up, especially if outside temp is hot. Getting around 95 here now, and summer is just starting! Not driving more than 45 minutes, sometimes I get back to the shop, and coolant can be heard boiling in the upper hose.
Yes, have a spring in lower hose. 50/50 mix of anti-freeze, and distilled water.
Yesterday, I took a spare thermostat, knocked the guts out, and made a restrictor plate out of it. Full time circulation, with that, went for a drive. Stayed alot cooler, but still getting too hot, when 95 comes around.
Any thoughts, good or bad.
