Here's a pic of where the engine is stamped with the CID and SN (not always).
The available IH SV8 engines... 304,345 & 392 CI
I strongly suggest getting a copy of the trucks Line Setting Ticket,which is the spec sheet for IH trucks as they were built.
Here's an example;
Here's a link with a basic explanation of LST's and what the codes are for;

viewtopic.php?f=18&t=3240Here's how to obtain a copy;
viewtopic.php?f=20&t=1374&p=8229&hilit=line+setting+ticket#p8229There's a slim chance an original is still in the truck,it would be on the back side of the glove compartment,to open push the clip on each side "in" to release and it will flip fully open. LST's located there are about 3"x8" and may be hard to read. Better to get a full size (8x11) printed copy from the WHS.
Here's something that should prove very useful.
CTS-2306 Service Manual;
https://archive.org/search.php?query=su ... TS-2306%22It's in 6 parts and can be downloaded free.
Here's a link for the MT-136 IH parts manual
https://app.box.com/shared/otkihx6yoa/1/24829736Unfortunately some sections are incomplete. Also free to download.
I suggest reading the General Info 1st.
The carb is definitely a Holley if a 2bbl (either a 2300 or 2210),the exact model is dependent on engine and more info would be needed to look it up in the IH manual. Easier way is find the pn's on the unit and go from there.
If it's 392 it will be a 4bbl and either a Holley 4150 of Carter AFB.
Unless it's a 392 with a 2bbl, (Not OEM) no adapter plate is used OEM.
If you need more help IDing the carb. I have the info.
For posting questions on this truck please use the "1000 Series" section in the future.

Never argue with a fool...
If you don't have anything nice to say...say nothing.
If you don't learn something new everyday...you weren't paying attention.
THINK! Be sure brain is connected before mouth is in gear.
