Default Ls7/ ls3 compatibility?

Pretty sure they will since they are both the short style injectors

Do you know if I will have to get adapters for the rail? I tried to mount it to the intake and it fit one side. The other side the holes and the studs did not line up.

Now that I think about it I had to order specific LS7 fuel rails for my setup to be used with the Fast 102 LSXR for LS7's because the mounting pattern was slightly different.

So the injectors will work but you'll need LS3 fuel rails.
