I know  when you have a big aft facing flat area like the back of a Corvair 
(and most  cars), you're going to have a nice area of dead, recirculating air  
there.  Now the chances of the exhaust finding its way back up the hood  to 
the inlet grill is small but if your lid seal is bad or there's some other  
leak, it just might find its way in.  Unlikely but  possible.


YES THERE IS A DEAD AREA BEHIND THE CAR.
 
Last time I looked at my Corvair the air inlet to the engine compartment,  
either EM or LM, it wasn't located on the rear of the car. Just tail lights  
there. The air flow over the deck lid is very strongly toward the rear of the  
car. The exhaust gas could churn around behind the car, but it is not going to  
make it forward to the air inlets. The side exhaust will most likely get 
sucked  into the vortex behind the car.
 
So if you have no tail lights or a bad seal at the rear of the engine lid,  
you could get exhaust into the fan and heater. But as the original post stated, 
 there's no way, during normal operations that the exhaust is going to make 
it to  the air inlet while the car is moving.
