I figured using an IR thermometer would be able to see the temp of the heads in different areas, not just the coolant.
the thermometers we have today, back then were like nasa special issue... now we can order them from china for 15.00.....

My work has a good one, cost them 80$. Might ask to use that one, or just get one myself.

They do come in handy. And yes technology has gone leaps and bounds from yesteryears, I remember a comment my father once made "in my lifetime I saw the muscle car wars, saw a man put on the mood, the evolution of the microchip and computers, and the space station being built"

To put this into context, my old man was 56 when he passed away. In less then 50 years look how far we advanced.

There are things we can do today that once was thought to be next to impossible.

Here is a link to an article about cooling a SBC. There is a little info on modifying the cooling system to balance temperatures. May be useful for those contemplating this.
http://mysite.verizon.net/vzezeqah/s...ingsystems.pdf

If you would like to see this implemented on the engine go to page 14 of this article:
http://mysite.verizon.net/vzezeqah/s...les/camaro.pdf

Yes... I understand this doesn't relate directly to the 6.5. Just something you can use for ideas.

OK, I will join in on this but I don't have first hand info on this mod as I haven't done it yet and haven't seen any really good pics of everything that is done, ( I can understand it better with pics).

What if a second crossover, one like the one on the front, used on the rear of the heads with the same t-stat in it was moded to fit and the hose was tied in to the front return hose going to the rad, or maybe the return side of the heater hose?? It would seem that the hot water would leave the heads faster and still not have vapor locks in the heads. and on a side note, I have thought about using the non water coolant - don't remember what it is called.

I might not be thinking about this the right way, just tiring to understand this bypass idea..

Chris

Then you might remove too much coolant from going to the front of the heads causing the front of the heads to run hot.

Coolant circulates from the front of the block, to the back, up to the back of the heads, and towards the front of the heads and out the crossover.

Some say removing some coolant from the rear helps, some believe adding cooler coolant into the rear helps cool the heads better.

I understand the adding method, to me the removing coolant idea seems bad, but as we all know things are not always as they seem.

I'm with Chris. Pics would help

I've been thinking about doing this mod myself as I've had cooling issues with my truck when towing a relativity light camper.
I've already got a list of things to mod and replace, but I want to add this to that list

It has been quite a long time hasn't it bud?

Doesn't seem like that long. 2007 for both of us. Has it really been that long?

At least your still driving the demon, although i am planning on getting Christine back up and running(or should i say stopping, damn brakes) soon. Gotta shake the cobwebs off the ol' girl.



As far as coolant into the radiator, hot coolant enters up top, and the bottom hose is supply into the WP.

Not sure why they run it that way, and not hot coolant out into the bottom of the rad.
I can't think of a reason why.

Both my old Subaru and my friends 4.7 V8 dakota have the t-stats on the bottom not the top, and i believe hot coolant enters the bottom of the radiator. Not 100% sure though, but it certainly looks that way.

I know this subject has been around a while now, I have the Heath write up on my pc and it shows that the single stat works best... I have talk with Heath & Kennedy & Schoolcraft, and they still stand by the single stat setup and being that this is what is on my 91 truck, I am going to stay with it.

I have seen some pics that show how the setup is and works. I am going to cement my block i'm my build and I am going to have 2 water filter setups in the system so we will see how things work out. And I will use the non water coolant, I will be the genny pig for this one,

Just for some of you that care---or don't care my build is starting now, I will try and start a thread on all 3 sites I am on, but it is going to be a lot of typing time to do this, the main thread will be on another site but I will do my best to paste everything to all 3 sites as I go. some of you are on the other sites as well so you will see it. The main build will be on (TDP), and this one and (TTS). I have been asked to do the thread on the free forum on TDP so with a lot of help from a few of the members there, I will.

Chris
