I had a problem with a 440 in a 56 Dodge pickup. After about 20 min of driving the temp would be at 230. Tried reducing the speed of water through the system with no change at all changed the thermostat. No help. When changing the thermostat noticed a couple of inches under it in the housing there was a hole drilled into the other side (inlet). Tapped and put a 1/4 pipe plug in the hole. That cured the problem. The engine would go up to 195 (that was the thermostat) and not go any higher. Can someone tell me why they drill a hole from the inlet to the outlet side of the water pump housing? Anyway, overheating problem solved!

I did NOT read every post.
This is an area that seems to be over looked.

Is it running too lean?
What do the plugs look like?
Did you try ti richen it up some?
I had a car 20 years ago that did exactly as you have.
The edelbrock carb was far too lean, richened it up and all was good, even with the air conditioning runnig!!!!!

I would like to know more about this solving what sounds to be my problem.

I'm having an overheating problem as well and I put an infrared heat gun on my exhaust pipes just coming out of the heads and I'm getting 675ish on all but #6 is like 550 and # 5 is so hot it don't read (over 800). Now I'm wondering if maybe my stock cast iron intake manifold is warped or cracked somewhere? I'm also going to try tapping and plugging that hole in the WP housing.

I didn't put a gun to mine, but after holding the RPM's at 2500 for a couple of minuates (in park) the headers were glowing red. Could it be lean, or too much timing? Car runs cool at low speeds, but on the freeway at higher RPM it runs HOT!!

Glowing headers sounds too lean.

Too lean or LATE timing can cause it.
I still bet it is way too lean.
Simple to richen it up some to try!!!!

I think I agree on the too lean. I took my distributor to have it checked. It is set at 15* initial and 34* all in by 2500 rpm. If this is right, my headers are now glowing even more. I will try to richen the secondaries and see how that goes. Any other suggestions??

What does the converter have to do with running hot.

Produces a hell of a lot of heat esp if it is a 4k stall. It would always slip on the street. I don't know how that can really be that streetable.

But how does that affect the engine?Seems like only the trans would need a good trans cooler

You can run a stand alone unit but that is a lot of heat. If the lines currently go into the radiator they are basically heating up the coolant. I just caught the tail end of this thread so I'm not sure exactly what he has for a setup.

underdrive pulley? That's what kills my cooling system...

Funny thing was id pull off in stop and go and it would go to 185-190 degrees, I get back on the highway (granted doing 70 mph taching 4000 rpm) and it crept to 215-217 degrees and stayed there.


sure sounds like classic inadequate flow in the cooling system (usually the rad) but I'd pull the plugs and check the turning torque required on the front 1&1/4 bolt ASAP right when it's good and hot and maybe 215-217 is not a deal breaker but to me that is too hot.

Went through all of this with by 440 Dart. My overheating problem turn out to be low fuel pressure ala too lean. It would change depending on what day it was, hot at idle one day, hot driving the next. New fuel pump and it was cool...really. Doesn't matter whether it makes sense or not, that's what fixed my overheating.
