74 Scamp gen 3 swap help

Pretty new to this forum, and mopar, so bear with me. I'm am going to be doing a gen 3 5.7 swap into my scamp and I'm trying to make it as problem free as possible. I know it's not going to be very cheap. I'm overseas currently and I am trying to use my time putting together all the parts and learn as much as possible before I come back. My questions are; is there a kit that can be purchased that makes everything go smoother or does it have to be peiced together? I saw that BPE has a kit but there was no prices so I can only assume it's ridiculously expensive. Also what are the do's and do nots of the swap? What fabrication is required? I want to use the stock k member for now, and also the stock 727 (if it is possible?) if there are questions I should be asking please tell me.
