Swapping pre 74 slant six engine to 75 + engine

I'm mostly into the "early" "A's" so I'm not sure about the oil pan. The only things I can think of that might be different are
1) oil pan and pick up
2) Motor mounts and/or brackets
3) carb/choke linkage
40 Distributor points/electronic
These are all visible and can all be transfered between engines
