parts list for swap ?

Yes I already have an Edelbrock 600 good to go. And I already figured I'd have to budget 200 bucks for an intake manifold. I'm just wondering how much cobbling I'll have to do? I wanted to kind of put the LA engine in there because I had it, it's running and I figured it would be easy. If I'm going to have to do a crap ton of work to make it happen then it's kind of a wash. I wasn't really trying to get any kind of power upgrade or anything like that.
J par..... you tore your Duster apart like a model kit. There is really no more work putting a 318 mag where the LA 318 was than if you went to an LA 360. Same everything, and if you want to take a "sure way", get a 360 truck pan and pickup tube, and put them on your mag with the LA front. While the intake and timing cover is off, throw a cam with a snout in there and put it back together using the LA front. DONE! READY to RUN! PRESTO..... lol

P.S. - you will get a power increase. Best of all, you won't need to add extra Zinc :D
