Re: [T3] 74 SB w/ IV engine

<x-flowed>As to the 914, the air intake is in front of the engine and the exhaust 
system is under and stretched behind the engine...big difference 
compared to a 411/412 set up.  The 914 can get its air from above via 
the engine cover or, primarily, from below the car.  Later models have 
two flaps under the body, before the engine bay, that assist in 
delivering air to the engine bay.

I'm not a Bus expert but I believe the exhaust system is sealed from the 
engine compartment by engine tin.  Cool air fills the engine bay via 
side air ducts.
