I have heard that the 1957 F-birds had special lower compression cylinder heads. This seems to be well documented. I have also heard that the F-Birds had a special 312 block however, i can't find any mention of this in the literature. Is it true? If so, how is the F-code 312 block different from other 312s?

Steve, I am by no means an expert so you can take this with a grain of salt. The Supercharger heads are lower compression and would carry the part number EDB-D on them. I actually have a post in here (right below yours in the technical forum) requesting additional information on the EDB-D heads I just acquired. To my knowledge the block does not have any unique identifiers and is exactly the same as any other 312. The F-Code cars also have unique intake manifold, carb and numerous other parts.

Guys, read this first... http://vs57.y-block.info/vr57pinups.htm

I am not aware that there is a different block for the supercharged engines, the parts manual does not call out a different block with supercharger.

I've been following Ford y-blocks for 50+ years.  Like Randy, I have never seen anything in print or heard anything from anyone considered knowledgeable that indicates that the engine short block assembly (block, cast crank, forged rods, cast pistons) was different in any way for any of the '57 312 engine options.  That would include ALL '57 Ford single four barrel carburetor ('D' code), dual four barrel carburetor ('E' code), and the supercharged ('F' code) engine options.

Hope this helps.

John Mummert's web site at  http://www.ford-y-block.com/  is a compilation of a tremendous amount of Ford y-block data.
In his Technical section, John indicates that the block casting letters for '57 312s were:
                          ECZ 6015-B coupled with ECZ main bearing caps
                          ECZ 6015-C coupled with ECZ main bearing caps

the short blocks for all the 57 312's are the same. Heads and intake were special.
