Please Help! Holley Terminator 2x4 mounting issue

[62_BattleBird]

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.

These work. Out of stock but if you have a mill they are easy to make.

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

Awesome, thank you. I’ve got it set to notify me when in stock. If the Offy ones don’t work, I’ll give these a try.

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!

       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.

Well, the Offy solution didn't work as it seems they're simply an adapter to shift the carb back about 1/2in. I also purchased an adapter plate from Alkydigger (https://www.alkydigger.net/product/TBS4300.html) and wasted almost $300 there lol, so it looks like I'm going to have to learn how to make my own adapters. I'll update this thread as I make progress for anyone interested.

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!

Do yourself a BIG favor and pick up a spool gun for welding aluminum. I am also a novice welder and found a couple hundred dollar spool gun allowed me to actually lay down a pretty impressive weld (for a novice) on aluminum.

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

I believe there are two Offy options, one for sideways, one for setback/forward.  Could you have bought the wrong ones?

If you wanted to switch throttle bodies, these will fit the tunnel wedge easily. I understand if you want the 4150 look, though. Just throwing it out there.

     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.

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.
