360 swap?

Picked up a 76 motor home 360/727 combo for my son's 70 swinger. Wondering what will need to be done to swap it for the 340/727 combo currently in the car. I know we will have to get a 360 pan, but will we need to get a new pick-up also? Read on here the air ports on the heads will need to be tapped and plugged. What about motor mounts? Also we have Performer 318/360 intake. Will this work well with the factory Carter carb? Anything I'm missing? Thanks for any replies.
