Yes, it will fit, but will probably not provide a performance improvement.
the edelbrock website should have that info.
The firing order is the same.
I have never seen a cast iron edelbrock intake so I would think not.

Yes. Consult Edelbrock's website for specific details.
Or from autozone you can buy a quadra-jet to standard adapter plate if you don't have that edelbrock or if you have a holleythe intake manifold is hopefully what youre talking about and the answer is noAnsweryes you can. if you have a stock intake manifold, which uses a quadrajet carb, you can use edelbrock part number #2696 which you can buy from summit racing (www.summitracing.com). it allows you to use an edelbrock performer square bore carb on the stock quadrajet manifold. for that motor i recommend the edelbrock #1406 which you can also get from summit.

Here is the installation instructions for the Edelbrock Performer aluminum intake manifold for a Ford 351M/400...hope it helps out. http://www.edelbrock.com/automotive_new/misc/tech_center/install/2000/2171.pdf
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.
