camshaft part numbers

[speedo]

I've searched but cannot find a link to camshaft part/casting numbers. I need to find a specific cam, and need to know what I am looking for as I search. TIA

Andy...thanks.
Tom's spreadsheet is a great resource. Looking at it I am wondering why the right side cam for the 67-68 L, and the 69-73 E is the same part number (901 105 110 05), but the left sides are different? Also the same for the right side cam for the 69-73 S and the 2.7 RS (901 105 168 00)...left sides are different? I was always of the impression that the S profiles were all the same...Int-Ex-Duration-Separation. Those numbers all look very, very close. I am asking these questions as I just picked up another 69 S longblock which is missing the right side cam (missing a couple other things too) and I want to find the proper cam. Looks like any of the S cams will work , but the correct part numbered cam would be 901 105168 00. I do get the fact that the early S cams were not MFI and the later were...therefore the later S left side has the MFI drive on it...and a different part number as such. And yes Dave I will send you the engine serial number when the pallet arrives.

Smog pump nose on the L cam required a different mold than the E cam. As a result a different casting number was issued.

The later S cam I cannot tell you. There is no obvious reason it would need a new casting number.

I recently have run across a couple sets of NOS 964 camshafts with rather unusual part numbers:

964 105 247 86
964 105 248 86

964 105 247 83
964 105 248 83

964 105 247 84
964 105 248 84

I was told due to the last two numbers being double digit they are factory racing cams. I do have them sent out to WebCam to have them plotted, we'll see what comes back, has anyone seen these before?

Here is an updated copy of the camshaft cross reference with a few more blanks filled in.

Regarding Lars' questions about the S vs RS profiles.....As best I know the profiles are the same for all early S and the RS cams. I do not know why the LHS RS cam has the unique P/N.
