Carburetor help

[Dogdish95]

So my Holly 1920 body Broke on my 1969 Plymouth Valiant and I am awaiting a replacement. In the mean time I picked up a Carb off a junkyard dart. I have search and can’t quite find how the heck to hook this thing up. I have no clue what goes where with this... any help would be appreciated

That's a '74-up Holley 1945 carb. It's going to have a lot of vacuum nipples not applicable to your '69 car. Carburetor operation and repair manuals and links to training movies and carb repair/modification threads are posted here for free download; pull down the 1945 one so you can identify which port is what. Connect the "OSAC" or "Distributor" port to your distributor. Connect the "PCV" or "Crankcase" port to your PCV valve. Leave the bowl vent nipple (if this particular 1945 has one) open to the air. Plug all other vacuum ports on the carb. You'll need a different choke thermostat, which is just as well because yours has been brutalized and won't work properly even with a compatible carb, which this one isn't. The factory choke thermostat compatible with a 1945 isn't compatible with a pre-'72 exhaust manifold. To run a Holley 1945 you'd need a № 1234 electric choke kit, but to run a Holley 1920, Carter BBS, or Stromberg WA, you would need a № 1231.
