Default Cam?

I have a cam that I was told came out of a 1970 350/300 vette.
The # I see on the cam shaft are GM58 6930 A27
Can anyone ID this came for me.

I fixed it for you.

The "929" cam was used in most all base engines from 1967 all the way through the early 80's in ANYTHING including station wagons. The CASTING NUMBER you see is "930". Throw it away.

TNX....but I've always heard it referred to as the "390" cam due to the intake lift of .390...
