The old carb has issues with the inlet threads. So if you are meaning to convert the old one, I can't cheaply do that. The choke was ok on the old one mostly. Bought the new one pretty cheap, cheaper than having those inlet threads fixed. Right now with property taxes due I am having to stay as low buck as possible. I am going to have to put off a new fuel line too maybe till next month. I guess I blew my budget buying a alternator belt. Well that and a welder with my student loan money.
And thanks for the tip about the wire. At least I have wire and connectors that should work on hand.
The new one looks clean on the bores. Just cruddy on the outside when it got here. I am hoping I can avoid rebuilding it for awhile. And it shouldn't need much tuning as it was also off a 472. Now I know they are probably set differently, but shouldn't be as bad as say one off a small block chevy. And the nice thing is it also has the idle speed up for the ac that was mostly missing from the old one. One rod and part of the diaphragm was still there when I got it.
Thanks again for all the help and suggestions.

Shown at the bottom of the page, no idea if your Caddy is among the "Many other applications available", but the difference will be mainly in the length of the arm up to the choke linkage at the carb- http://www.carburetion.com/quadrajet.asp

Connect the + wire on Choke to a fused Ignition activated 12V+ source.
Don't tap + wires to Coil or Distributor.
There're 2 different style Choke connectors:
The Coil, Linkage & Cover on Intake can be discarded.
The Vacuum connections should be fairly easy.

Converting from external choke quadrajet to electrical choke quadrajet
I have a mostly stock 1968 cadillac. The original carb has the external heat riser choke. There is a coiled spring that sits down in the manifold. It is typically called a divorced choke. I have purchased a later quadrajet from a 1974(I believe that is how it decoded) cadillac. It is the later style electrical choke. I know it should be a pretty simple conversion, but I am not sure where to run wires to/from the choke. I think I can figure out the vacuum hoses out if I am careful on the switch over. So what do I do about the wires? Anything I should know about the vacuum lines?
