it is fore a boss 302, they are very rare. i once tried to buy a trans am preped full race 69 boss 302, the motor was scattered but it had the cross boss intake on it. the car was always a race car and was fully role caged. it was a competition orange car . this was several years ago ,i offered the guy $3000. for it . he told me he didnt want to sell it . ****ed me off when i heard he later sold the car for $2800
if i rember right the carbs are made by autolite . and i believe it was part of fords experimental line
lots of money if you do find one. just think how i felt missing out on the whole car.You can see the Autolite stamp on the carb in the pic =)
So it is for a Clevor/Boss type motor. You are correct, if you look at the part number you will see it has the experimental part number designation.
The worst part is now that I've seen one, I really want one......
Quoted only info I thought was relevant to the thread.Ford 302/351C CROSS-BOSS intake plus Autolite INLINE 4V carb - NOS
We have come across these rare pieces of Ford Racing history - new, unused, and sealed in the original parts boxes. This auction consists of a Ford "Cross-Boss" intake manifold (base plus top) PLUS a NOS matching Autolite inline 4-barrel carburetor, complete with original jetting and small parts kit. This intake fits Boss 302 engines, and was also used on Boss 351C engines using an adapter plate (not supplied).
Autolite Inline 4-V Carburetor:
The Autolite Inline carburetors came in two varieties - 850 cfm (P/N D0ZX-9510A, using 1 11/16" throttle bores) and 1425 cfm (2.25" throttle bores). This auction includes the larger version. Similarly, there were "early" and "late" versions of these carbs - this carb is a "Late" version (label indicates 1973), and it features a tunable idle circuit with two removable jets per venturi. The original jetting kit features a variety of idle, air bleed, and main-circuit jets, as originally supplied by Ford. Much of the criticism of running these on the street involved the "early" versions, which had no dedicated idle circuit. This carburetor is new and unused, and was found sealed in a plastic bag direct from Ford. Ford Part Number DOZX-9510B, it is dated 5/29/73 and features serial number 20390. The tuning manual for these carbs is available as a reprint and also may be found online at https://www.shoair.com/pdf/autoinlinecarburetor.pdf
This carburetor was shipped to Swanson/San Jose Ford of Los Gatos CA, via Air Freight (San Francisco), which of itself is pretty unusual. We also have the matching 875 cfm carb, available (with a matching top) on a different auction (290608309292). Both carbs were shipped via the same airbill from Ford Parts Central Office, Livonia MI. Team records indicate that engine and car testing was taking place at the same time at Laguna Seca Raceway, located a few miles away near Salinas California. The smaller carb and top combination apparently was used in that testing session.
Manifold top:
Part number DOZX-9C483-A, NOS, found sealed in original box.
Manifold base:
Very lightly used, apparently in a testing session. Box not available.
Tuning Aid (?):
As part of this shipment, Ford Parts also included a base-plate for use under the carburetors. It features two very small ports on either side on the inside of each bore, counter-bored and threaded 1/8" NPT on the outside, intended for vacuum take-off, instrumentation, or ??. We are including this piece with the auction. It also is lightly used.

"There were two models of the Autolite in-line: P/N D0ZX-9510A flowing 850 cfm and D0ZX-9510B flowing a whopping 1425cfm. The smaller one was intended for the Boss 302 in Trans Am, hence the development of the Cross-Boss intake. The larger one was intended for the Boss 429. Intake manifolds of the 'bathtub type were also available from Holman & Moody for the 429 and Bud Moore for the Boss 302 and the 351C.
Ford DOZX 9425-A and DOZX 9C483-A - lower and upper intake manifolds for inline 4 barrel Autolite carbs, used on Boss 302 and 351C-4V (with spacer plates)
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. The carbs themselves use 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."
sweeeeet. and look how clean and simple.
Mmmmmmmmmmmm.
I just saw that one of these intakes went for almost $5k on ebay. Here is the description that went with it:
Quoted only info I thought was relevant to the thread.
Those are fuel rails, and that aint the carb in this thread. (Notice the lack of accelerator pumps on the driver side of the carb) That is a inline 4 hole throttle body on a Rousch offered engine that sells for ONLY 18k.What are those thing that look like fuel rails in the picture Noobz347 posted?
was that shop called ford power parts? i think that was the name .the guy used to stop by when ever he was in the area. i havnt seen him in quite a while. he had all kinds of ford goodys.yes in fact i have seen one, well three actually, and all in the SAME place. there was a ford parts store in the LA area years ago that had three of them for sale, complete with the autolite inline carbs. two single carb intake tops and one twin carb intake top. i wish i had money at the time as all three set ups would have gone home with me, including the five inline carbs that they also had sitting around loose.
