Thats what I would do. Go aluminum and get one that will run LA or Mag. NOT that chinese pile of crap that keeps popping up on ebay. Claims to be good for magnum engines. If you google the reviews of it, its terrible. Poor sealing surfaces, poor castings, ect... Cant remember the name brand of it, and I cant find one on ebay right now, but beware. I am running a 5.2 Magnum in my '78 out of a 2000. I ordered my intake from an ebayer, but it was a new in box edelbrock. Ill use it again when its time for the 5.9 swap. That is assuming I dont get my hands on a cummins before that.
