I did look at the report. Its a very through document.
Much more information  than what my CamDr would produce.
I agree with Ted that the cam analysis that was done to your stick matchs the specifications for a regular 1957 cam.     Nothing race special about it.

Somewhere along the way the original cam supplied in that tube had to have been swapped out.  Now a virgin 1957 cam is nothing to sneeze at.
Many folks would want an original/new 1957 cam for their rebuilds as they are no longer availiable .

And the elusive 285 H.P camshaft mystery trudges onward.

Based on the reverse engineered specs you provide, my thoughts goes toward the original camshaft being swapped out for the one you now have.  The specs on this camshaft does match the specs for the 1957 B, C, D, & E code engines which makes it not matching the description on the container.  That now brings up the next line of questioning.  What is the exact history on this camshaft and how did you come into possession ot it?

It says:
Special Racing Camshaft
EDB-6250-D
Can't read the entire B7A number.

Oldmics, did you see the attached cam dr report?

Let me know your thoughts.
Thanks

What is the number on the tube ? Is it B7A 6250-C ? Cant quite reaad it on the picture. Interesting that Ford would have called a stock 57 camshaft Hi Perf

Those cam specs match up to the 1957 EDB camshaft specs.  That camshaft would have been used in the 272, 292, and D and E code 312 engines.  Compared to the 1956 and ’58 and newer camshafts, it would be a high performance camshaft.

Hi Guys,
So, I posted in this thread 5 years ago about an NOS Ford "Special Racing Camshaft"  I had. Here is a cam spec pulled from the core(see attached file). Also I re-posted a picture of the camshaft tube.  Anyone know what grind this actually is???

Thank you! When I get block back from machine shop will degree cam and put info on this forum.

Crane Cams made a cam with those specs. back in the 60's and 70's.  They called it SS-300-A, .451/.451 lift, .016/.018 lash, 300/300 duration, 225/225 duration at .050, and 113 LC.  Good idle and torque.  I had one in my T-Bird.

Just disassembled 312 that I know has sat for 37 years. Block is ECZ-C intake ECZ-B heads small ECZ-G but cam has SS 300 and m9535 on end and YB-1 CWC cast into it. Lift measures .288. So .288 x 1.54 = .4435 - .018 lash = .425 ish. Is this the RPM 300 Isky cam? Could it be the 285 hp cam? Bore is 3.860 with stock appearing pistons crank is 3.440 stroke but is ground .010/.010. Its supposed to be from 57 bird block still has traces of orig red paint but heads have orig yellow paint like 272?
