Crankshaft Identification

One of my crankshafts has a casting number of what looks like
C4AE-6503-G
The C4AE and G is clear, but the 6503 might be wrong.

I have checked all my books and can not find this number.
I know it is a 1964 crank, but I have not found any listing for this crank.

The 427 C4AE-6303-G crank is forged steel and was part of the High Riser 7000 rpm kit. Was also installed in the C3AE-6303-V High Riser spec'd for the Tbolts and 4v NASCAR engines. SAE 1046 forged steel and very RARE to find. Your normal aftermarket parts book might not have that listing.

Thanks,,
Looks like I have another rare part. Someday, when I die, someone will get a lot of good stuff. My wife does not have a clue as to what race parts cost. I will roll in my grave, if she sells the 427 or 428scj for $100.
Oh well, I won't be here to complain.

On a side note the C3AE-6303-V number is not for highriser engine assy. I'm not able to edit that post. I had that number tagged with the C4-G number with no further info. I'd think a earlier crank number tho and the crank the C4-G replaced. But the G crank info is correct.

I went out and looked at it again, and it is a C4AE-6303-G. The sucker is beefy.
