Need help planning 6.1 swap from 340 4spd

My plan is to swap a 6.1 hemi as minimalistly as possible then when money is available do a front and rear end conversion with the RMS stuff, what all would I need to go from my 340/A833 to a 6.1/A833 and be running and driving. I was looking at some of the Mancini swap mounts have many of you used them to swap or do most people go tubular k member at the same time?
