671 can't be run without supercharger aka blower. there is no such thing as a naturally aspirated 2 stroke detroiter.
There is no intake or exhaust stroke, but the exhaust valves open a few degrees before the piston clears the intake port, and air is forced through the entire cylinder. This is what gives detroiters that 'sighing' sound.
You could add a turbo on top of the blower, some of the 6-53's were sold that way.
A mechanically-scavenged (i.e., employs a blower) two-stroke Diesel engine is considered to be "naturally aspirated", vs. the same model which is turbocharged (i.e., 6-71 vs 6-71T). There are MILLIONS of naturally aspirated 2-stroke Detroit Diesels in the world (I own 2 of them). Also, the intake & exhaust strokes are shared with the power & compression events; the "sighing" sound you refer to is the sound of the roots blower.
ive domne it once before u ened too roll the forks back when its unchained lift up teh forks a lil bit then lean foward and lift the forks again its kidna hard to explain
I don't suck at life because I said a truck's sound isn't the greatest. Guys I wasn't trying to be mean or anything I was just saying, that trucks sounds unusaul. Get over it please.
It's almost a haunting sound but very distinctive

If the engine in this truck was a Detroit 6V-92TA 335 hp, would the truck sound any badder than it is already because of the truck's exhaust system?

People who grew up around the old Detroits probably think the same thing about alot of the newer engines with the way they sound.

Sounds like a Detroit to me... I would rather see him put dual straight pipes on it than getting a quiet exhaust.
