7.5 swap to 7.3

Hey I’ve got a 1997 F350 with the 7.5l 460 and an automatic transmission, I’m starting to look into the idea of swapping the engine for a 7.3l diesel engine of a similar year, I’ve never done something like this before so I’m trying to figure out everything involved, such as would it bolt up to the transmission I already have and would I need to bulk up the front suspension to handle the weight? I’m going to continue to doing research into it but wanted to see if anyone here has some good insight into it, thank you for your help
