I have been having a heck of a time with my cooling system and I have now tracked it down to this point, my guage is off a little bit but not bad. I ran the car today in the 88 degree weather and she started to heat up a little bit especially at high RPMs but not bad, went to the rad shop and borrowed their thermal ( infrared ) thermometer. I checked the engine over and it was pretty much 188 to 192 everywhere except right in the middle and on the top part of the intake manifold directly across the carburetor, both sides of the intake manifold in these locations showed a temperature of 237 degrees . What is causing this and what is my fix. I have the stock 65 mustang cast iron manifold and a autolite 4100 1.08 venturi carb. I am worried that I will start to cook or already have cooked some top end components. Please help me figure this out.

That's normal. That's exactly where your exhaust crossover is located. {uses exhaust heat to heat your carb on a stock intake}

Can I assume then Steve ( not questioning you just trying to learn ) that these are normal temperatures ? How high can the temperature go in that area without causing problems ? As you remember my engine is taken out .060 over and you know what has been done to it, with the engine done like this what should my temperatures be at, under more or less normal conditions with some WOT involved when I get the urge to play. What temperature should I be at when I am on the highway and cruising at about 3000 to 3500 RPMs. I am also going to install a tranny cooler when I get back from camp, don,t think this will help keep my rad temp down, but I really prefer to have a separate tranny cooler, what are your thoughts on this? TIA

Steve is absolutely right; your temps are fine (especially concidering the ambient 88* temp).

I've had good luck installing external trans coolers... your radiator no longer has to exchange heat for two components

Did the road test and temp test again, outside temperature is now at 86 degrees. The temp around the engine ranged from 197 to 203 everywhere except at the intake manifold and it was at 247 to 251. I am still running mid-grade gas, 160 stat and my timing is still at 17 initial and 38 all in at 2900 to 3000 RPMs. I ran the car fairly normal with a couple of quick throttle shots, but I did have some stop and go as well as stop and park a couple of times for just 15 minutes or so. How do these numbers look to you ?

200* certainly won't hurt anything, but I too like to run them cooler than that. Like suggested earlier, definitely pull a few degrees of timing out of it and run some better fuel. Should be worth 10* or more

How much timing do you think I should pull out of it Todd?

At least 4 degrees, 6 would be better. Windsors don't like or need much timing. I run mine at 34 degrees overall, but that's with quite a bit more cam, exotic heads, deep-breathing exhaust and a BIG carbuerator

I believe Alex runs his S/S motors at no more than 32*, and he's got dyno access

When I had it at 12 - 13 degrees it would not run worth a crap, what would be the reason for this ?

It sure needs the time down low...

Is your dist vac advanced?
If so, are you setting the timing with the advance hooked up or capped?

Hmmmm... I'm running out of ideas

I bet that motor would love a set of good headers
Easier said than done, I understand. Opening up the exhaust would dramatically improve the motor's ability to evacuate spent heat energy much more effeciently though

[/B]


Headers = no collector plates . I will do the trans cooler first, highest octane gas I can buy at the pump (94), put a proper guage on the car so I can actually read my temp instead of the stock guage, In will then see how the temp goes then take the timing down to 14 or 15 to start and see what happens. Any other suggestions you have would be greatly appreciated.

They do random checks, but there are also people that turn you in. The worst thing is, if you are involved in an accident, even if it is not your fault and they find something on the car that is not suppose to be on it, they void your insurance and you have no coverage . I,m wondering if my exhaust manifolds are causing some of this problem because they do not flow enough, especially at higher RPMs. This 289 is basically a cast iron stove with those exhaust manifolds and stock intake manifold. Any thoughts on this angle ?

If you cant use headers you may want to consider 351W or HiPo 289 manifolds. They are a little more free flowing than the "log" manifolds that you have.

John,

I do not see anything wrong with 200, you are reading the metal temp, not water temp with the infared gun, and it is going to be somewhat higher. Did you shoot the upper radiator hose or the top of the radiator? This would give you the best indication of actual water temp. If the water temp is under 190 I would not be concerned. You can safely run 210 on the water with the proper antifreeze mixture.

I have always ran 14 - 16 inital timing with no problems, if I heard detonation I would drop the timing back 2 degrees at a time until the detonation went away.

Beat me to it. I'm not familiar with Canadian mod laws, but surely you could pass off some better flowing hipo exhaust manifolds as stock, right?
