swaping a 360

Hey guys well the other day when i was moving around my cuda, i got frustrated, the car runs like crap, it idles crappy, aw, well i was gonna swap a 360 into it, i was gonna build it first, but hell maybe i should just swap it in place of the pile 318. The 360 needs a timming chain, and id probably throw a 4bbl on her, i think it has one, but id swap it anyways. The distributer will swap from my 318 to the 360 right. How do i remove a distributor w/o screwing something up and install it in the 360. After thinking about it maybe the 318 has a cam or something it runs like **** but once it moves its...alright. or just a pile. also the oil filter i believe is leaking when I start it up, oil drips from around that area. is it hard to swap the adaptor for the oil filter over to the 360. also the 904 is pretty shot, i can just swap the bell housing from that 904 to another and run that, it seems pretty shot, I know the 318 is pretty tight fit on the drivers side, how will the manifolds work in that case, i dont wanna put on super restrictive manifolds so it kills the engine, could i self port the manifolds or at least try to as far as a dremil would go. But on the other hand if i decide to build the 360 which will be soon not to far down the road. I will have to repull it, i guess i should just get the drivers fender first before thinking of driving it. :) getting ahead of myself
