good deal.I’m using the output wires from my Holley Sniper system
74 Dart , 440
I’m having the same problem. Have 1row Griffin radiator, this is the biggest I can put in. Have March pulley system plus Magnum Force coilover , rack and pinion K member. Support pipes on the side power steering pulley close to fan. Have high volume water pump, high flow thermostat. Did ok in cool weather but live in south Texas. Have even put that stuff that is supposed to cool down 20 -30 degrees. Looking into another radiator. Run two radiators. Going to go to the Martin Bros. Shop and ask them about what I can do. Some people are saying it’s ok to run 195 - 210 , I don’t like that high
On my 1972 dart with 440, i fought overheating for years sitting still or low speeds. I had the original small block radiator and shroud, a flex fan and no thermostat. I finally got tired of the hot running and did some changing up. I installed a nice aluminum cold case radiator with the big cooling tubes, used the original shroud again, and found a factory 7 blade fan, AND installed a high flow miloden 180 degree thermostat..it was the best thing ive ever done to this car! It will sit and idle all day long in 100 degree Tennessee heat and never go over 180 degrees and as long as the car is moving it drops down to about 170. I wish i had done all this years ago!
my opinion, your fine.So at what temperature will an engine overheat and cause damage or break down? My 440 (stock radiator and 7-blade fan) normally runs at 180-200 degrees. Was doing a charging test idling in drive for 15 minutes and it crept up to 230. As soon as I started driving, the temp dropped back to 180. When should you pull over?

t-stat might have not opened sitting? 180-200 is fine. 230 is fine if you are not running that temp all the time. The concern I have is if it continues to creep beyond 230 if you leave it sit even longer.So at what temperature will an engine overheat and cause damage or break down?

So how do you install a one piece radiator shroud? The space between the radiator and blades is about 1/2 inch. I doubt I could get the fan off bolts out, then back in. Does the shroud bend? Mancini Racing Radiator Fan Shroud

Can't you get more clearance without that 2" spacer?
That fan is probably too close to the radiator anyway. The fan will need to sit so that it's about 1" inside the outer lip of the fan shroud. Remove the fan and spacer, mock up the radiator shroud, determine how much fan spacer you need to locate the fan a 1/2" to 1" inside the shroud if possible, then remove the shroud from the radiator and hang it off the pulley. Install the fan and proper spacer (if a spacer is even necessary), then slide the shroud back over the fan and up to the radiator and bolt it on.
And the good news is that your heating at idle situation will likely improve quite a bit with a good fan shroud.
Yeah exactly!
You take the radiator out, slip the fan shroud over the fan and let it hang on the pulley, install the radiator and then attach the shroud to the radiator. Any more questions?

He asked. Make sure that you cardboard your pretty radiator fins.
