Porky Pig has the real deal heat exchangers but calling their output anemic is being generous. The flappers close completely so that is not the issue. On my SC with backdated heat (no blower motor) and SSIs it will cook me to death. Never been able to stand it even with the levers at 3/4s.

So what do I need to recheck on Porky?

its not the heat exchangers (as others said) its the fan.

Get a more modern fan.

Grainger has 12v fans that blow way harder.

LOL.

The heater fan on a stock 6 is also the engine cooling fan.
At low engine speeds the output is not that great.
With stock 6 HEs it should be enough to be warm at low speeds and very warm at higher speeds.
If the boxes are patched and loose on the exhaust headers you could be loosing a lot of flow.
