1264
3 03
9089

Thanks a lot !

EDIT: There is another number in front of the cam:

09199
1448*

This is what I found on my 97 LT1 cam.

GMPT - BC - 15 - - 755
There is a number 8 on the back end.

I looked around online and can not find much else besides the specs.

I was in the same situation and bougt 3 LT1 cams to compare, basicly the base cirdle is smaller on the lt1 cam.

The fuel pump lobe was like grinded down on all the cams, 3 lt1's and stock lo3.
2 lt1 cams had the long dowel pin.
