Added heat to my header'd -4 Options

So this weekend I did a lot of tinkering to put my curiosity to bed on heating a car with headers. I remember reading from Dan Root's -6 conversion thread that he welded some pipe to his headers and pushed air through with a stock heater fan.

Sorry no pics now but, I can explain somewhat. I tacked a bent pipe in perhaps 20 places along the length of this bent pipe to the left hand primary tubes. I did insulate the header plus pipe in 1" header wrap. When I attached the blower and ran at idle for maybe 10 minutes I measured the duct surface temp at the driver footwell to be 87 deg. with a good supply of air flowing out. I do think that perhaps the dual oulet blower ( 1 side is capped) from an early car does blow a bit too hard and may need to throttle down that motor or perhaps replace with a bilge blower.

I do realize that this is not ideal and the C0_1 hazard but these are not permanent and I will inspect in the spring when defrost is no longer needed for corrosion etc..

Now, if I do replace the fan or throttle it down, more heat soak should occur between the heater pipe and the air traveling through. Additionally I have not road tested only idled so I anticipate more heat as I piddle around town regardless of cfm through the hose.

Does anyone have an idea about how much cfm the 71 dual oulet blower should blow?

You could build a stainless steel container attached to the header with welded tabs. The container should be two sided - one side with the cockpit heating air and the other side where the exhaust pipes pass through. It would be something like a cockpit heating system found in general aviation. The flexible heat tolerate hoses on each end and tied to the butterflies and the fan system. Nothing new about this type of heating system. Also, you should use a carbon monoxide monitoring system in the cockpit.

The worse case found in such a system is the possible leaking as the header system wears out. Periodic inspection could be used to make sure the exhaust side is ok. I personally do not like exhaust heating source systems. I am doing something a little different since I am interested in both defrosting and heating. I live part of the time in the hight country of Arizona. Yes, we do have cold and snow in the winter months in Flagstaff - 7,000 ft.

Best of luck and with the proper materials should work great. Always be aware of the carbon monoxide!!!!
