I came across this explaination on a Chuck Zeiler photo on RRPA.
"They were powered by a De La Vergne four-cycle eight-cylinder in-line diesel
prime mover coupled to Westinghouse electrical gear, producing 1000 horsepower,
or 60,405 pounds of tractive effort. It was found that the single exhaust stack
tended to create back pressure, and as a result, tended to overheat. The CB&Q
(and other railroads) solved this problem by installing four stacks on many of
its VO-1000's, resulting in a noisier locomotive. Some railroads went so far as
to add eight exhaust stacks, a practice Baldwin called, "hot-rodding"."

IIRC, I believe that there are 'dimples' on the underside of the hood to mark
where the stacks should go. I do not believe that all units got this
modification or what time period they were done. Looking at photos on RRPA,
some units still had the single stacks into the mid 60s when they started
leaving the roster.

Subject: [CBQ] Q VO-1000
I have a Stewart HO Baldwin VO-1000 painted as CB&Q #9365. Holck Vol 1, p
58, shows a photo of #9365 at St Joseph in 1960 with four exhaust stacks
appearing to be mounted slightly towards the fireman's side. How much to
the left were these stacks mounted? Holck says that 9350-9364 had 11 small
louvered ventilation openings, and 9365-9379 had 15. The Stewart model has
the 15 openings. The other obvious difference is four stacks versus
one. Were certain units made with one stack or was this a change over the
years in service? I am modeling about 1950, so I am assuming that four
stacks would be correct for 9365 at that time. Would that be correct?
