    An LS3 intake will not fit on an LS1 engine the ports are different.

    LS1 cars have cathedral port heads and LS3's have a more traditional square port.

    Well I am glad you have a matching engine

    Just use a T Junction and pull vacuum off a different port.

    Did you research the swap before actually doing it bro? You probably need an adapter because it was Drive by wire?

    Maybe this will help out.
