Added heat to my header'd -4 Options

[geniusanthony]

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?
