65 Valiant swap 273 to a 360

So I bought the 74 motor home 360 and TF yesterday and am making a list for parts needed for the swap. I need a car oil pan, and pickup for sure but I'm not sure of what I can swap off the 273 onto the 360? I just replaced the fuel pump on the 273. Will that pump work with the 360? Also the timing chain cover will probably need to be swapped but I don't think the 273 cover will work with the 360? Any other help/advice would be appreciated.
