    I have posted this before. But here is one on my 53 I ran til recently. Video thanks to Jeff Rice. Yes this manifold was designed for a Aeroquad 450cfm carb. It was offered in a kit by Offenhauser.

    Hi Skinny,

    Did you ever run that Offy manifold? How did it run? The layout of the ports is interesting, if the exterior is any guide. The end ports look to have a smooth sweep, and the inboard ones kind of sticking out "like the legs on a dead sheep."

    regards,

    Dan T

    Bill,
    Bring that Morgan intake, as well as your car to the SE Stude Swap Meet (and _ _ _ _ race) next April 11th and 12th near Savannah.
    We can weld up amd mill down your Morgan and mount it for some testing!
    Open invitation...
    Jeff

    the pattern is still there. As a result, it is quite thin on one back edge and it is off of the car
    currently , and will be repaired soon . The adapter plate is the same as previously
    shown . They did a bad job of blending the adapter to flange , and I worked that over.
    It worked well on the car , running low 14's at 94+ mph .
    There's a Jeff Rice 2V modded 4V manifold on there now . The Morgan is 14 +/- lbs lighter.

    That's why I asked about the existence of an "early" WCFB bolt pattern. For some reason, I don't have one in the collection. It took some research, but as Jeff says, there were two WCFB patterns. The rare '52-54 square bolt pattern was used on Buick and Packard straight-eights, Cadillac and Olds V8 as well as this Offenhauser Studebaker V8 intake.

    The much more common '55-67 WCFB rectangular pattern, the same as the Rochester 4Jet, was used by Studebaker, Packard, Chevrolet, Pontiac, Buick, Chrysler, DeSoto, Dodge, and Diamond T.

    (BTW, I've never even seen a Stromberg Aeroquad. By the time I was seeing Buicks, I guess the Aeroquads had all been replaced by WCFBs. and the later cars all had Rochesters.)

    Next question, I thought I could remember having an Offenhauser intake manifold with the late bolt pattern. Did Offenhauser change the bolt pattern after '55 when all the OEMs changed?

    If it wasn't an Offenhauser, what other Studebaker V8 aftermarket aluminum intakes had the later bolt pattern?

    On the shelf or on the cars are a dozen Rochester 4Jets, six WCFBs, eight AFB/Edelbrocks, and they all have the same rectangular bolt pattern. When the AFB came along in the early '60s, they used a wider pattern, same as Holley, but retained the narrow pattern beside it. This was a benefit, because with a few modifications, the AFB could bolt on to 4-bbl manifolds back to '55 but the Holley required an adapter.

    Thanks to Jeff for reminding me and we all of the two different WCFB bolt patterns.

    This should help clear things up a bit. The Stude Offy was designed for the Stromberg 4A Aeroquad used on 52-54 Buicks. Carter also builds a WCFB with the same pattern as the 4A. Here's some pics of my stock Offy with and without an adapter. You can see the big difference between the 4A pattern and the large WCFB/AFB/Holley patterns. I picked up the adapter from Vintage Speed before I found an off the shelf 4A pattern WCFB from a closing parts store.

    That Packard manifold (pictured) does not have the same base bolt pattern that the early Offenhauser has.
    Yes, it does have the narrow AFB pattern, but that pattern is way longer than the early AFB or Rochester that I put pic's of earlier.
    The early pattern is a square one. You can see the difference on the Offy's that I put the plates on.
    See the countersunk Allen bolts? The other (outer holes) are the later, narrow AFB pattern.

    Here's an Edelbrock AFB with both early and late bolt patterns.

    As we can see, using the four inner holes it drops right on the early carb bolt pattern manifold.

    You know more than I do, Jack.
    I'm just trying to help Roy out, and answer questions.
    That's why I posted pictures.
    Lot's of info out there on the 'net.

    The old Offy has a narrower square bolt pattern than the narrow AFB/wcfb.
    it probably took a Rochester 4GC carb, or a Carter 'early' WCFB.

    Hey Roy, When I had my Offy, I bolted up the adapter, then used a hole saw to open up the bores to match. Then use a grinder to smooth it all out. I ran it that way for about 15 years with no trouble.

    If it was an Offy intake for a Stude (without an adapter plate) (like the OP has), it probably took a Rochester 4GC carb, or a Carter 'early' WCFB.
