Re: new lower intake manifold and new plenum

Do a search in the aftermarket forum. Personally I went with the AS&M Bigmouth manifold. Screw Edelcrap and SLoPpy.
There aren't any aftermarket plenum's for us unless you change the whole system. Most people around here just port their plenum's.

Again, you'll find a lot of info about this in the aftermarket forum.
