Ford Cross Boss Intake, Autolite Carbs
Has anyone seen? or even have one of these?? Never knew anything like this existed. This is the only time, I wished I had a SBF in my car :MECOOL:. Comments? I'd love to hear what you guy's think of this piece of history. https://bringatrailer.com/listing/or...50-carburator/

Just google Autolite inline carbs.
Twins would be nice if you can find them. Not as tuneable as Webers. Gary |
Friend of mine had an inline Autolite in his garage. Didnt have the original intake, but used a blower intake with a flat plate milled for the carb to mount to. When I asked about it years later, his crackhead brother had taken it and ditched it for scrap.

You could get the system in a couple of configurations, single inline and dual inline. Both systems were intended for BOSS302 applications. The tuning was very similar to 48IDA Webers.

Thanks guy's, so far. One thing that I don't still understand is why only one, or two, 2bbl's.? What was the reasoning for this system? When we talk about the 48IDA, we have 4-2bbl's. Now a day's I like it just for the cool, or wow factor, I would bet if you lifted 500 Cobra hood's in this day and age you wouldn't find this intake under any of them. I was around during the org. Trans-Am day's and don't remember any team running this system. And I don't think the reg. said anything about just one 4-bbl or in this case 2-2bbl.. as all I remember were the cross-flows or straight 2-4bbl,'s. Cheers Tom.

Member 427S/O ? converted an FE crossram to use dual inlines... http://www.clubcobra.com/photopost/d...69Image005.jpg |
Each inline is actually a 4 barrel carburetor.

The Cross Boss manifold and single 875 cfm inline 4 barrel Autolite carb was Fords successful attempt at "bending" the rules for racing while using a single 4 barrel carburetor.
The Cross Boss is a single plane crossram manifold with removal top to allow lower half to be fitted to the engine. All 4 barrels of the carb are in communication with the single plane manifold like a typical Holley 4 barrel manifold arrangement to meet the rules. But the 4 barrels placed inline gave better distribution front to back. The manifold also made more power than previous 4 barrel combinations. Eventually, the combination was banned. The Cross Boss also makes more power in a single inline than two 875s in an IR setup. The 1425 versions have 2.25in (57mm) butterflies, and are more suited to IR, especially with large engines. Barry Grant manufactured a similar concept carb named the BAD MAN, 4 barrel inline. Gary |

Had they be accepted for Trans-Am I am sure you would have seen a lot more of them and continued development. |
Thank you so very much, Gaz64, and of course Mark IV that answer's my question's. completely. That's why this site is just "The Best" I still wish I had a SBF, to set this on ;)

I'm not sure but I believe there were issues with tunning these "back in the day".

I believe one version didn't have idle circuits. |

The idle circuit, is really the low speed circuit. The engine runs on this up to 2500 rpm or so, for light throttle use. Gary |

Gary is correct and the automotive journalist, as so frequently happens, is wrong. Either misinformed or not fact checked (equally likely) prior to publication.
An engine can not run without an idle circuit. Ed |

Kelly notes the many little details that separated these early units from the later one which were actually sold over the counter |
Funny there is a mixture screw per barrel below the throttle plate in each barrel, and an idle air bleed in the air horn per barrel next to the main air bleed.
Historical Info - Welcome to the Inline Autolite Carburetor Site: www.InlineCarb.com Read under Early Production D0FF9510T Looks like an idle circuit to me. Gary |
