I did not find it, re read my post.

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.

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.

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.

Thank you for eMailing Randy.I do appreciate it

Since I have communication with Randy I will ask about the "E" on the camshaft.

Be interesting to see where this goes.

Specs in my literature for the EDB-B cam are as follows which differs slightly from what’s posted above:

 

Cam lobe lift int & exh – 0.273”

Int opens… 22° BTDC @ 0.015”

Int close…  58° ABDC @ 0.015”

Exh opens.  58° BBDC @ 0.015”

Exh close .  14° ATDC @ 0.015”

Int opens ..  18° ATDC @ 0.100”

Int close…  18° ABDC @ 0.100”

Exh opens . 26° BBDC @ 0.100”

Exh close..  26° BTDC @ 0.100”

The cam will have an “E” stamped on the nose of it.

 

Typos in service bulletins are not unheard of though.

 

It would be nice to know if the cam in that kit does indeed have the “E” on the front of it.  And being Cam Doctored would verify the specs as I’ve reverse engineered several cams now that did not match up to the original specifications.

Oldmics:

Randy e-mailed me you two had touched base, I had e-mailed him your request. I had voluntered to get the cam "cam doctored" But that probably will not happen. I do not think I would let the parts leave my sight with out cash in hand.

EDB-6250-B 1/14/56 B6A-6250-E 260/260 .278/.278 112 .019H/.019H 22 BTDC 0.0150 58 ABDC 0.0150 66 BBDC 0.0150 14 ATDC 0.0150

Here are the cam specs from the F.E Site for the package, not as wild as I thought it might be.

awesome find, just curious enough to wonder what he paid, I'd never tell!



Yesterday at the Tulsa Tbird Regionals I looked at a 56 bird with the original "dealer added 2-4 setUp". Indeed a rare setup for a 56. see if I can check the head #'s today.



Lots of other good stuff there as well, 2 blower cars and several e-setUps.



I'll try to get some pics t.

Those C heads reportedly were milled .060 at the factory for the kit.  If the original owner got the kit for $300, he got a deal.  When Hot Rod Mag reported on Emil "Bird on the Wing" Constantino's engine build, they stated that he had to give $400 for the kit, and all he wanted was the intake.
