Ted: Would the kit have been a late 1956 one or early 57? The heads are 1956 passenger car, (possibly milled as noted) but the Cam is apparently a 57 "D" code, advertised at 256 degrees as used in 312s, & probably used in 292 & 272 applications also. While a rare and interesting find, it wouldn't appear strictly speaking, not to be a racing kit. As you say, it would be interesting to have the cam checked out for spec's by yourself or maybe John Mummert in CA.

Paul.  I don’t have literature identifying specific part numbers of the individual parts used in the kits but there’s a good chance the kit components were upgraded over time.  I would suspect that the overall kit numbers changed when the kit components changed.  I do have a Ford letter here to the dealers dated Feb 4, 1957 offering the B6A-9000-B hipo kit for $100 whereas they had been previously priced at $315.00 dealer net.

That is interesting about the two cams part number being the same (EDB-6250-B) and having two differing grinds.

Randys cam does not have an "E" stamped on the sprocket hub.

I"m gonna guess that even though the two cams share the same part number,the stamped "E" designates the difference in what the grind is.

PF,the cam that you mention (the 256 duration unit) is part # EDB-6250-C which is not the camshaft found in the kit.

Hope this helps.

I did not find it, re read my post.
