Those markings do not mean anything to me.  Reverse engineering the camshaft specs either by using a Cam Doctor or measuring the camshaft lobe profiles within an engine would tell more about the camshaft at this point.  If I could borrow the camshaft, I would be interested in reverse engineering the specs from it.

Does this info tell you anything about what the cam is?

There are some other markings I did not notice before. There is a yellow paint marking highlighting the other marks. They appear to be a fomoco logo with either 32 or 82 above it. Any clue??

Looks like there might be some additional markings on the EDB end. On the side of the bearing journal surface.
Might have a FoMoCo script and other markings.
Any chance for some additional hi definition pictures?

OK I took the cam out and inspected it for markings. On the cam end, it is stamped I-815. I also found markings EDB near the opposite end. Does this tell us anything? See the attached pics.

Thanks

I believe that you have an understanding of the situation.
As you have surmised , the first letter of the VIN code is a reference as to what engine is installed into the vehicle.
While most of us Y Block fans simply refer to  the standard horsepower 312 engine"s cam as the "D" code camshaft, that cam was also used in the 292 engine which has a "C" designation in the VIN.
It was also used as the cam in the "E" code VIN, 270 horsepower engines and also in the 300 horsepower standard "F" code VIN designation.  Other camshafts were also used in higher horsepower versions of these engines.
The origination of this thread is about what camshaft was used in the 285 H.P. version 312 engine.
I think the confusion lies with the way Ford has two different identifications of their parts, as Parts and Engineering numbers and also Ford Known Parts Number.

Yep - confusing !

Man is this a confusing subject!.. However, I think I've figured out why J.M.'s 2006 article referred to the std 1957 EDB cam ( as listed on the chart) in the following write up as a "D" code. That  Letter is on a car's Vin #, designating a car equipped with a 312 engine! !..  It was not intended as a reference to the supercharger cam. ..

The cam that was sent to me by Wally Kirstein years ago was made on a Ford core and had FoMoCo script marking. The specs were correct for the production 290° degree cam. I would have to find the cam to see what the suffix after EDB was.
The later over the counter cams were not on Ford core, as I recall after 17-18 years.  I would expect to see CWC and probably YB1 on an older aftermarket core. These markings are generic to the core and do not indicate what the grind is.

The EDB designation (which is the engineering number) for all standard Ford 1957 automobile engines coded as "C"= 292 and "D" = 312  both engines used camshaft EDB-6250-C.

That translates to Fords "Known Part Number" as B7A 6250 B.

I am not familiar with John"s article (and he obviously knows WAY more about Y Blocks than I do)
I would have to guess that he did not include the suffix# in his description about the "C" and "D" code engine camshaft.

The camshaft tube displayed in the post by 57ECODE shows a picture of the tube which has the engineering designation of  EDB D printed on the label.
That crosses to Ford"s  part number of B7A 6250 C which is the blower camshaft.

NOW - which version of the blower camshaft inside of the tube can only be distinguished by the markings on the camshaft stick itself.
While the label identifys it as an EDB D unit ,inside it may be something different.

Hope this clears up any misunderstanding.

O.K. now I'm confused, based on Oldmics posting.  In the article & chart by John Mummert I referred to above, his chart shows the "std" 1957 cam as an EDB, but the chart does not include any suffix # or letters. Than he refers to it in the article as the 245 H.P. "D" code cam.. Is that in error?
