Do I need to make any changes to the frame to install the 4R70W? I am bolting it to a 351W, are there any significant changes that I would need to make (other than driveline lengths) for this swap to happen? Is it a direct bolt in? Thanks.

No frame but the bolt in crossmember will need work.
Unless you have a body lift a little floorboard clearancing is needed as well. Where the transmission tunnel hump drops down to floor level.
