The 5500 quantity produced for the 1957 model year are the numbers that I have from a Ford source.
Remember that count would also include over the counter sales,warranty replacements and a 3-5% casting imperfection.
That would also take into account all of Fords installations of "E" code engines-T Birds,Rancheros,passenger cars,etc.So about 5000 "E" installed setups from Ford.
The only hard evidence of Buddy Barr being involved is from a paragraph in the 56 Hot Rod (I"ll have to see what month)magazine tieing Buddy Barr to the Mercury M 260 intake manifold design and casting.
Ford racing had a racing relationship with Buddy Barr,Ralph Moody and a few more folks,all of whom were in California at that 1956 era of time.
The "lore" is that Ford farmed out the race only design in late 1955 to both Edlebrock and Buddy Barr with a promise that they would produce all of these style of manifolds for Ford.
Buddy produces the 1956/ M 260 setup which looks suspiously like Edlebrocks FM 255 intake.Thats the manifold with the overhang on the rear carb.The 56 Merc setup used a pair of bakolite spacers under the carb just as the "E" code passenger car did.
Its not very good for driveability (remember this was race only stuff) and Dearborn Steel Tubing gets involved for the 57 model year,driver quality stuff.
The diamond with the "S" in the center is Dearborn Steel Tubing"s casting identification.
I"m under the impression that Buddy Barr did the Ford 56 manifolds and know for sure that Dearborn Steel Tubing did all of the 57 "E" stuff.
Theres at least two different castings of the Ford 56 manifold (I have both).There is NO evidence of a Dearborn Steel Tubing I.D. on either of those manifolds.
I dont know if all of the facts will ever come to light.There were at that time many aftermarket companys producing a version of the dual quad manifold.Just not with the blessing of Ford.
I contacted Buddy Barr castings years ago with no luck and I am planning an invited trip to Hollman and Moody for a look see in there library.
