Ok, im preppin a 345 for install into my 74 Scout with a 727/d20 , I have the option of installing the original 2 barrel manifold or a 4 barrel manifold I have on another donor motor.
I have the linkage set ups for both. I guess my question is , if I set this up with the 4 barrel manifold and linkage, will I be ok puttin the 2 barrel on it til I can get the tq ready for install. The adapter is relatively cheap. I'm mainly concerned about the linkage. I have all parts for both setups so I can change it up later but if I can do it once that would be better.
And having a 3inch body lift gives me plenty of hood clearance.
I've read the threads on the tq and I'm gonna check this thing out good before install, it ran great when we fired it off, but I think it could use a kit anyway. Thanks guys!!!
 
I'd go with the spreadbore 4v manifold and adapter. You could run it that way forever, and once ya have a functional spreadbore carb that gives ya the swap-off option!

The actual throttle linkage/kickdown connection points are the same! A thermoquad for an IH app has a throttle lever that allows direct mount, though some of those used in pickalls have a "chrysler-type" lever extension which is no big deal to fab or buy.

The kickdown linkage also mounts at exactly the same point on the rear/driver side of the intake. There is only one throttle cable used on all variations so no change there.

The spreadbore manifold uses the same choke stove for the divorced choke also for either carb, if ya use an adapter, ya "might" be able to re-bend the rod on the choke stove to allow for the increased distance between the choke link and the manifold. If not, just weld in a short extension to the rod.

The body lift is the kicker onna sii!!! With that setup ya can do anything! But the kickdown rod down to the throttle pressure lever might need to have a segment spliced in.
 
Thanks m/m thats really what I wanted to do so it would be easier to change over later. Was just worried on the linkage thing. Gotta get busy gettin the intake off the donor motor. Thanks for the info.
 
My comment regarding that both manifolds use the "same chokestove" is not really correct. Each carb uses it's own dedicated/calibration chokestove, what I should have written was that the chokestoves interchange!

The chokestove for the tq carb May or May not incorporate a "heater" element along with a remotely-mounter thermostatic control. All that schnizz if for emissions...it has nothing to do with performance/drivability so it can be deleted or not used according to availability/functionality!

What is needed though for either setup, is a functional choke stove to operate the choke link...however ya can achieve that! It closes the choke plate when cold, and opens the choke plate when warming up!

Hope I didn't confuse ya!
 
No confusion here. Us southern boys are pretty good at figurin stuff out. Once again thanks for your help. Gonna pick up the adapter plate Monday at the local speed shop , 18 bucks not a bad deal, and get the intake cleaned up to go back on.
After that its time to yank the 304 and stuff the 345 back in the hole.
Do ya think I'll need to do a jet change on the 2210 before I even try it or should I run it and check the plugs , I'm thinkin they only go up 1 or 2 jet sizes between the engines so maybe it'll be ok.
 
Regarding the 2210 carb, the main jets sizes did not vary amongst engine apps. Main jet sizes did vary slightly by list number and model year though as that was for emissions calibration, not what was best for overall engine performance!

Run it!!

I'm interested in how that carb works on an adapter. I do run various adapters around here so I can run multiple carburetor apps on one single engine. Idle quality is always ok for test purposes, but I've noticed a bit of a glitch with "some" 2v carbs during tip-in when run on a 2v-to-4v adapter. I rationalize that as due to the uneven charge distribution through the dual plane manifold created by the adapter.

I'm not saying this won't work for ya...but I would expect it to be "different" compared to your previous experience with that carb! And knowing that the carb is completely functional rules out any other problem!
