Indiana Pook, and the quest for heat

[Pookapotamus]

Do you mean blend as in outside air and inside air? Yes that is still in place, the door I cut out was for heat vs cold, but since the valve in the engine compartment stops the flow of coolant to the core it should not be a problem.

That is the one I was talking about. How are you going to adjust temp? I think that AC core will put out a lot of heat

[Pookapotamus]

Was planning on running the cable that used to control the heat out to the valve for coolant flow.

[4.3LXJ]

OK, that would work. You will need to change that valve though. I suggest a valve for a 73 Dodge Polara wagon for that

Thanks steve

Sure can't say I do things half assed! Looks like I need to clean up some wiring while I'm in this far

[Pookapotamus]

New modified heater box is installed, I sure hope this works cause it's a holy pain in the rump to swap out!

Will be cleaning wiring up tomorrow, and then cutting the gauge cluster apart to replace the gauges with the ones that were below the glove box.

It will work

Well, now that Mort is running again I finally got to test this.

And... Well.... FAIL!

Super hot coolant going into the a/c core and super hot coolant coming out!

Does not transfer heat fast enough, basically warmish air coming out.

So I guess I go back to a standard heater core, modified to fit in a more direct air flow of course. Kinda wondering about having 2 heater cores in it, but I think with better air flow, the stock one will be fine. Maybe change up hoses and valve to provide more coolant to the core.

Pook, if you go to two cores, do you know about counter current flow?

[Pookapotamus]

I'm picking up what you're putting down Steve, any idea where to find heater cores by size? Space I have to work with is 3.5x11x10

[Pookapotamus]

Also trying to find a napa part number for this

[4.3LXJ]

Not really sure on that Dana. The best I can do is tell you how to use countercurrent flow to get maximum efficiency out of two cores

[Pookapotamus]

Looks like summit has generic cores

[Pookapotamus]

About the same size, but twice as thick
