RE: [Chrysler300] First Factory Dual Quads

["Rich Barber" <c300@xxxxxxx>]

Always worthwhile to explore, document and disseminate these details from
the '50's.  I thought the '55 Chrysler 300's came out in February--perhaps
Cousin Gil could advise of the earliest documented production dates and
earlier prototype dates.  I was also under the impression that Cousin Briggs
Cunningham engineered and developed the full-race cam and dual quad carb
setups in the early '50's and that Chrysler adopted them.  It seems I have
seen that either Rochester or Delco made all the "batwing" air cleaners.

I've seen batwings on dual quad Chevy sedans, but there is apparently not
enough room for them under a Corvette hood.

Other dual quads seem to come to mind--"E" class T-Birds as per: 

This stunning factory original "E Bird" is one of just 1,499 produced. 1957
was the only year for the "E" dual quad and "F" supercharged T-Birds. Here
is the production rundown: 
Base C code motor, 292 CID, 2 BBL, 212 HP, 3,300 produced. 
Optional D code motor, 312 CID, 4 BBL, 245 HP ,16,423 produced. 
Optional E code "Special High Performance" motor, 312 CID, 2x4 BBL, 270 HP,
1,499 produced. 
Optional F code "Special High Performance" motor, 312 CID, 1x4 BBL,
McCullough Supercharged, 211 produced. 

And then, the '64 Buick Riviera as per:  

The Riviera continued with minimal trim changes for 1964 including the
discontinuation of leather upholstery from the option list, differing mainly
in substitution of the old two-speed Dynaflow-based Twin Turbine for the new
three-speed Super Turbine 400, which was marketed as Turbo Hydra-Matic by
other GM divisions. This was the first year that the Stylized "R" emblem was
used on the Riviera, a trademark that would continue throughout the
remainder of Riviera's 36-year production run. Under the hood, the 401
(6.5L) was dropped in favor of the 425 in³ (6.9 L) V8, with 340 hp. A 'Super
Wildcat' version was optionally available, with dual Carter AFB four-barrel
carburetors, rated at 360 hp.

I even saw a "batwing" air cleaner on an older Buick straight eight with
dual carbs.  Its air cleaner was rotated 90 degrees from those seen on V-8's
for purposes of space and/or access.

And, I'd poll the other hemi owners on this question:

Does anyone else have dual manual chokes on their 300?  Mine look pretty OEM
as they replace the guts of the automatic chokes with Carter plates and
spring-loaded shaft for the choke plate arm.  The car spent most of its life
in the Colorado Springs area and may have been a hard starter (still is when
it loses its prime).  The heat riser connection on the exhaust manifold is
plugged with an aluminum or SS plug.  I have read that the carbs on certain
racing and industrial hemis came without chokes, especially the industrial
units that were designed to run on propane or butane.

First dual quad car out of the factory is interesting to document, but the
fact that the C-300 and successive letter cars  blew the doors off of all
the others and the 355 HP racing version of the '56 "B" was the first
American car to be rated at over 1 HP/cubic inch remain chipped in stone!
NOT the fuelie '57 Chev's.

My angle of interest on this has been more about the '53 New Yorker Pan Am I
call 'Adam' being a forerunner of the fantastic dual quad equipped Chrysler
300 Letter Cars.  Didn't study what others were doing until now.

Since the '55 C300 didn't arrive until January it is probable that popular
availability of the '55 Cadillac Eldorado and '55 Packard Caribbean both
were on the market first.  Does anyone know introduction dates for those
special models?


The '55 Eldo and Carib both had dual quad Rochesters for their first time.
'56 Chevs offered dual quads.  '56 Pontiacs had a NASCAR package of 3x2.
The '57 Olds J-2 package was their first 3x2.  Studebaker's first dual quads
were the '63 Avanti R-3 and R-4 options.   I know of no prototypes or
experimental cars from any company that were publicly sold with dual quads
earlier from any other company. 

That still leaves Adam as the first factory dual quad car sold to the
public.
