The 700R4 that was rebuilt for my rod had a cracked bellhousing bolt hole lug. I used a bare block to bolt it to then took it to a friend of mine who tig welded it. After he was through I smoothed it up with a flap disc. After painting you can't even tell it.

Yep general aluminum welding rod, he wasn't concerned with what the aluminum alloy was. The crack in my case wasn't that big, only about two inches around the bolt hole.

Check it...

Cast aluminum

Other aluminums

Basically all he needs to know is that the case is cast aluminum.

If the guy is insisting on knowing what the aluminum alloy is, find another welder. It isn't that critical he know what alloy it is.
