It should be preset from the factory
You will have to look on the carb and get the numbers on it and then go to the Edelbrock website.
Yes. Consult Edelbrock's website for specific details.
none, unless the old carb wasn't working properly.
yes
With the edelbrock, use the vac line on the carb itself, It will be a small bore, 1/4 ( about ) vacuum line, and should be on the front of the carb.
holley makes carbs for all vehicles. the manifold on the caddy is set up for the carter afb, which edelbrock used as a base for their carbs, so an edelbrock will bolt right on. this is the route i took with mine. you will probably have to get an adapter to set the holley up on the square bore of the old caddy intake. the adapter should be available wherever you get the carb. hope that helps.
Pretty sure you can mount any standard flange or spread-bore carb on an sp2p. The Edelbrock website is an excellent resource for answering those kinds of questions.
I just rebuilt my Edelbrock 1405 Preformer carb. During the rebuild once I had the carb almost completely dissassembled I removed all four jets and replaced them with new ones from the kit.
adjustment screw is between throttlre linkage and carb body on the right side of the carb as you stand at the front of the car looking at the carb

If you have an edelbrock carb, remove the top of the carb, flip it over and there you have em! 2 floats! should be about 5/16 from the top of the carb i believe
