don't think it was "necessarily" the 2030 cam, but it was somethign close to it. The cam grinds are essentially identical, and it was manufactured by crane, however it's not called the 2030 if i recall correctly...but might as well have been.
I'll respond with the writings of the tech writer for the GM Performance Parts book section on our 60* mills.

SOMEONE has a knack for finding information....
. LOL but really, thanks dude. I had heard the 2030 thing and just needed to be clarified.

I can say the specs are probably nearly identical.
If ya score a 3.4 long block in great used shape you have cheap foundation for a very good power upgrade for your 3rd Gen F Body.
Just to point out, the GM Performance Parts book does state what I wrote, but GM Legal does not "allow" this GM Part numbered cam to be called the "Crane 2030 cam".
Hope this answer helps ya.
