FE "quadrajet" intake

[66ford]

Any idea what a cast iron 4bbl FE intake with quadrajet style induction would have come from (small primary, big secondary)?

thanks

A picture of one was posted on the old FE Forum a few years ago, I don't think anyone had an answer. I believe speculation was just an engineering exercise. Keep in mind Ford did use a Quadrajet on the 429CJ, along with various other "GM" sourced or inspired parts, like Saginaw steering sectors, Fridgidare A/C compressors, etc., so not really beyond possibly that they were trying it out.

I have a pic of one and the casting # begins with XE. Wonder if this is something out of the ordindary?

Certainly out of the ordinary.

I'd even say Bizarre

I will try to post pix later but it definitely says XE-94428, then a smaller SK-94430 next to it

Uhauls had them.  :-)

People have mentioned that before, however there are no listings for Quadrajets in the Ford Truck Parts book. There are specific listings for the 359 FT and F600 "Rental Trucks" as well as 389's and of course 330's, 361's & 391's and no Quadrajets anywhere. That doesn't mean it didn't happen, just no evidence in the parts book.

Missed the one on fordfe.com but I saw one on FTE with an XE casting. They were talking about a rental truck like Kevin said. What does #5 runner height look like? Seems the FT intakes were a little taller, if that was a UHaul or other rental makes sense it could be taller. Where is the heat cross over located?

EDIT: I have heard references of a factory Quadrjet on a California 428 and from time to time you can find a Quadrajet on EBay claiming California 428 and 429 Ford applications. Other than internet claims I personally have not seen anything other than a Motorcraft 4300D spreadbore. Could be this intake was designed for the Motorcraft carb?

Here's a picture of the printout I made in 2010 of the old FE Forum post, Hawkrods answer. XE number looks to be the same, maybe even the same picture you saw? Going by the heat riser location it's not a FT intake.

I just found that picture on Ford-Trucks.com. The stud layout is a spreadbore Motorcraft 4300D. The Quadrajet has a different pattern.

No, I'm pretty sure it's the GM Quadrajet pattern, it's not a spreadbore Motorcraft, one way you can tell is by the spacing of the primary bores - wide apart on the Quadrajet, narrow on the Motorcraft. Here's the picture from your link, looks to be the same intake.

Here's a '70's Motorcraft spreadbore.

Here's a link to the discussion on the old FE Forum, the oddball FE intake was a sidetrack from the original question. It's on page 2.

Your right. I was looking at the stud spacing and height and did not consider the Motorcraft throttle bores. I will take a look on a computer screen latter and see if I can tell how long the front studs are.

If you look at a 428Cj intake it has the same carb mounting pad, even though it's machined for a Holley, maybe they were also going that way if they had kept it in production.
