Showed my father the chart and he says C3AZ is a part # not an engineering #. Why do they mix part and engineering #'s on the same chart? Also on the AA he says his recollection is it wasn't 306 but 324.
C3AZ-AA = 306-306 cam, like C3AE-M
C3AE-AA = 324-324 cam, llike C3AZ-K
"AA" is confusing!

This MIGHT make a difference as to why? At the top of the chart it states "(Service Parts Only)". Maybe there are other charts and tables with additional info and maybe in the same book that page came from? And charts/tables with or for "Factory Parts"?

Yes the original 352HP and 390HP cam was cast letter K and the early C2AZ-A 406 cam was the same profile revised to adjust installed timing and then had the stamped letter A added. Apparently that became the service cam for the 352HP and 390HP.

Thank You for posting those pics from your dads books.
In your first pic what are those "Class" codes for and how do they decode and what do they apply/reference to?
Also, I LOVE the suggested prices that were listed.

Those are usually info passed on by someone at H&M to my dad or like these Crane cams with help from the cam master Pop Sullivan.

Crane cams and notes. Maybe you can pick up some of their methodology from them. I know different people used different approaches on cams.

Love the Ford comments on the C3AZ-K 324-324 cam:
"Should always be used for extreme competition"
"Poor Idle Characteristics"
And if you ask on the forum here, the assessment will be
"Daily Driver"
Those are some great pages. Note the 406 duration spec of 276-276, same cam as the 306-306 just measured at different lobe lifts.
Nice of them to include the .100" lobe events too.

I have the original used cam out of my 427 2x4 - if it's critical I can search for someone to measure it...?
Ok the only markings I can find on the cam are these:
FOMOCO
AB
Although the A & B are sort of backwards to each other:

Are you talking about like a mirror image on the B ? And/or the A being upside-down? Like how it is indicated on some of the cams in that chart I uploaded on page 2 of this thread?

Maybe a glitch or temp site issue? Maybe give it another try? I just uploaded a screenshot attachment in another thread with no issues. IF still having problems with your uploaded attachment disappearing, contact the webmaster (if needed PM 428kidd to get the webmaster's contact info).
Hopefully you can get the pics of your cam uploaded as I and am sure others would love to see it/them.

Wow.
According to Muscle Parts that VB marking (I.m using V for the upside-down A which is actually the symbol for "ALL") is the C3AZ-D 306-306 cam, not the C3AZ-K 324-324 cam often found in the 8v.
Near as I've read in 63-64 LoRiser, the 306-306 was standard on the 427-4v, optional on the 8v.
The 324-324-114 cam was optional on the 4v, standard on the 8v.
Our 63 427-4v had the 306-306-114 cam.
What year is your car/engine?

I bought the engine and gearbox a few years ago, it came out of wreck in the mid-60’s, but I don’t know if it was a 4V or 8v or a Ford or Mercury.
It had the 8v intake on it with original carbs but missing the distributor. Still had auto lite plugs, paint markings on the back, original head gaskets, bumper pistons etc.
Stripped it down for a reco and this (and other parts) was what was left over.

I just found my original 1964 427 low-rise 8v cam tonight. It has XBA cast into it. What cam is this? I had to replace this cam because it was starting to lose a lobe.
I liked this cam better than what's in the engine now, a Comp 282S

That's cool you found your original 8v cam!!! Bummer about the failing lobe. BUT, IF you really liked that cam and/or would like to save it, it MIGHT be possible to repair it (depending on condition and how bad the damages). Check with Oregon Cams on costs and feasibility for repairing it.
Looking forward to reading what others come up with about your cam and what is said about it.

In my records, I had two 324° cams:
C3AZ 6250-K
324 Dur 4V - 8V
.499 net lift .025 lash
Timing @ .050
In 10/56, 246 dur, 113 CL
Ex 58/7, 245 dur, 115.5 CL
96° overlap
This ones says it only needs 280 lb springs at 1.32
C4AE 6250-B
56/88 - 324 Dur, 106 LSA & ICL
88/56
112° overlap
.500 net lift .025 lash
But, I have nothing about the cam markings for the C4AE 6250-B

Just as a guess but, I think the "D" cam replaced the C4AE 6250-B as a the race cam.
The part number is referenced in dggilbert's HiPo catalog but no info on it.

Interesting fact. The early 428PI engines used the same C3 306 duration solid lifter camshaft lobe profile that was used on the '63-'64 427 engines. Sometime towards the end of the '66 model year Ford switched the 428PI to the 390GT hydraulic camshaft.
