360 engine question

Ok, have a question on a 360. I have a BB in my Duster and my son has a 73 Dart Sport he is going to put a 340 4sp set up in eventually. He is getting the urge to drive it now so I found a 360/727 with only 43000 miles on it out of a 79 RV. Problem is the sump on it is a front sump and it will not clear the k-frame. I was thinking of taking the oil pump and the oil pan from the 340 and putting it on the 360 to make this work. Will it work and if so, is there anything special I need to do to swap the oil pump. The other problem is the 727 I have is not set up for the tranny x-member and it has the wrong yoke on it so I am gonna sell the 727 and stick a 904 behind it for now so i dont have to change the tailshaft. What do you guys think about this. Any suggestions. Thanks
