Hi, I'm trying to get information on an "Autolite / Ford Carb I came across. Only thing I've been told is that it is from the 69 -70 vintage and was designed for trans am racing. I have pics and #s. Anyone here help? Thank you.

Yes, I've been told it is worth quite a bit. Once I learn the history on it I am going to sell it but rather than using "that auction site" I like to try to find someone who would be able to use it on their project. I personally have a #s matching 69Z28 Camaro and know what it means to find those hard to find parts. Thanks for any help.

IIRC, these were Boss 302 specific and were part of Ford's Muscle Parts program in the late 60's. One of the Boss guys on the Forum will probably chime in with more info. I recall seeing one on the parts counter at the local Ford dealer back in the day.

Also had a friend that ran one on his Boss powered drag car back then and it ran really well. All of the "bowtie" victims in his class claimed foul because they thought it was fuel injection.

I doubt you will have any problem finding a buyer. Good luck and take good care of that "Z"!

Get the numbers ready, then go to the Boss302.com website. Most likely you can post, and get a reply right away. Maybe even an offer on it.

I think they were used on "cross Boss" engines
Look at # 2440271262 on e-hay

Is it a DOZX9510-A? Or perhaps a DOFF9510-T?

Here is some general information, courtesy of Dan Jones, who has seen a number of these units over the years...



Autolite Inline 4 Barrels

The Autolite inline 4 barrel carbs were developed as a way of dealing with
the single 4 barrel rule imposed by the SCCA in Trans Am racing. The thought
was since any 4 barrel carb was allowed, why not make a unit with the barrels
all in a single row for better distribution. Inline carbs came in 2 versions.
Part number DOZX 9510-A, aimed at Trans Am and NASCAR racing, used 1 11/16"
throttle bores and was rated at 850 CFM. Part number DOZX 9510-B, aimed at
drag and unlimited class racing, used 2 1/4" throttle bores and was rated at 1400 CFM.

Ford developed a companion 2 piece Cross Boss intake for use with inline
carbs on Boss 302 engines and, with spacer plates, on 351C's. The basic
Cross Boss arrangement consisted of a lower plenum, part number DOZX 9425-A,
with a bolt-on top cover, part number DOZX 9C483-A. The removable top made
porting easier. In classes that were not limited to a single four barrel,
an 8V cover was available that, in Ford's words, "provides one barrel per
bore, located directly above the intake passages". It is unclear from the
photos I've seen if this arrangement used independent runners or a plenum.
In any event, inline fours could be adapted to Weber or fuel injection
independent runner manifolds. In fact, Ford recommended using two of the
1400 CFM inline carbs on a Doug Nash fuel injection manifold for all out
351C drag racing efforts.

The carbs themselves used a lot of off-the-shelf Autolite 2 barrel carb
hardware. There were also calibration kits (part number D1ZX-9S549-AA)
and gasket kits (part number D1ZX-9502-AA). These were strictly race
carbs and were never equipped on any production vehicle. Early versions
didn't even have idle circuits, requiring a delicate throttle adjustment
just to get them to run @ 1500 rpm. Later versions were equipped with
idle circuits that apparently worked quite well. In a 1973 test conducted
by Ak Miller, a 351 Cleveland equipped with dual inline fours was tested
against an open plenum tunnel ram equipped with a pair of conventional
Holley 710 4 barrels. Low speed operation with the tunnel ram was termed
"very poor" and the engine didn't start to work until 5000 rpm. The same
engine equipped with an independent runner intake and a pair of the 1400
CFM Autolite inline fours faired much better. Peak horsepower matched the
tunnel ram but, with the inline carbs and independent runner intake, the
engine idled well at 600 rpm and pulled evenly across the rev range. Low
speed operation was termed "fantastic". Ford had great plans for the
inline carbs but like many of Ford's better ideas, the inline four died a
premature death when Ford pulled out of racing in the '70's.

-------------------------

You might wish to contact Randy Dickerson, who likely has personal experience with these units.

Congrats on a nice find...
