I believe the Offenhauser #5880 provides the pair of spacers which offset each carburetor 1/2"; whereas the #5832 provides the pair of spacers intended to rotate the carburetors 90 degrees.  Unfortunately, the later is intended to be mounted to manifolds which present the 5-5/8" x 4-1/4" bolt Carter AFB & Quadrajet pattern, adapting the 5-5/8" x 5-1/4" Holley pattern for the carburetor mounting.   

     Hence, why one may find that the best way is to do a little custom welding & machine work to present that which is needed.   

     Oh,............I don't know what size of a welder you may have acquired but when welding aluminum, figure you'll need twice the amps as that of steel, and I would guess that for this job anything less than say 200amp. capacity just isn't going to be enough for a good result.

Thanks for the info Scott; that is indded the route I'm going to attempt. Thanks also for your insight on the aluminum welding; luckily I managed to get ahold of a 200amp welder so I should be good to go there.

I would buy a couple of 1" spacers. The biggest rough cheapo's from Summit.
And start from there.

I thought about doing this and may still go that route. I'm currently working on shaping what I need out of plates of 3/4in aluminum, so we'll see what happens. Thanks for the advice.

       Apparently the issue is solely the existing bolt spacing when the carb/T.B. are turned 90 degrees/sideways (though there may prove to be linkage issues impacting the plenum crossover/balance passage also?  )?  If so, then yes the 90 degree adapters are an option (check 4V bore positioning & sizing  ), but mostly back in the day of doing this we would choose to add material thru heli-arc welding in order to present bosses for the drilling and tapping of the appropriately positioned threaded holes.

       P.S.: I have a Tunnel-Wedge intake with two 850 C.F.M. "Center-Squirters" mounted sideways in this fashion hanging on the wall. 

     

Thanks a ton for the insight. I'm going to learn how to make my own adapters through trial and error (I possess none of the required skill at the moment ) as every other off the shelf solution has failed thus far. I just purchased a multi-process welder and a plasma cutter from eastwood and will begin to work on welding technique. I also bought some large sections of 1/2in thick (wanted 1in but it wasn't readily available on amazon) aluminum to practice on. With any luck I'll have a rough draft version of what I need in the next month or so, as I only get a couple hours a week to work on this stuff. Anyway, thanks again for your unique insight and advice!

These show as in stock from Offy but 200 bucks.  Don't know if the center rib would cause problems or not.

I just ordered a set and will be picking them up tomorrow (live about 20mi from the Arlington TX location). I figure I could cut out that rib if it interferes. Thanks a ton for the heads up!

Ok, please forgive my ignorance here, but as you can see from the pictures the carbs do not fit when mounted sideways (which they have to be due to space). I looked around for some sort of adapter plate or something, and was unable to find anything. I waited 6mo for this to finally come in and now I'm at a complete loss and hope I didn't waste almost $3k. If anyone has any advice at all I'd greatly appreciate it.

Would anybody be able to put me into contact with someone that has experience porting these heads and intake? I understand that Joe retired, and wasn't sure if there was anyone else that was the goto around here. Any advice would be greatly appreciated.

Since you are using a TW intake, it should not be an issue to mount them sideways.  Order a TR linkage kit for SBF/TR or 460Ford/TR from Weiand and you should be able to make it work smoothly.  The air filter housing should still fit for a 2x4 Ford manifold.  Joe-JDC

Thank you SO MUCH for the insight! I'll do some looking around and if you wouldn't mind, I'll reply to this thread with what I find to be sure it's correct. Thanks again.

I've ordered it from Summit. It's been a month and the estimated ship date was a couple days ago. Now the estimated shipping date is 7/27. So while I can't offer any help on how well it works, I can tell you order now if you want it because it's gonna be a bit of a wait.

That said my tuner who's been doing this since the 90's has stated the terminator x is THE way to go. He has promised me that I'll be VERY happy with it.

That’s great to hear! We’ll, not the delay, but you know what I mean lol. So to your knowledge this shouldn’t cause any fit issues? I guess I was worried because I’m still a bit confused on the mounting of the carbs on the FE (that it’s backwards or whatever) and it seemed these wouldn’t fit next to each other longwise (I hope that makes sense). Please forgive my ignorance, but I’m admittedly a newbie and this is my first build. Thanks in advance!
