Default 4.7l to 5.7l Swap

I have a 2005 dodge ram 1500 with a blown 4.7. I can replace the 4.7 but I thought I may as well do a 5.7 conversion being the issues I hear the 4.7 has. I have done a little research but keep getting mixed answers to what all would be needed for the swap.

This is what I think the most accurate answer is, Can someone please confirm?
5.7 Engine, Full wiring harness, ECM, alternator,compressor, Power steering pump, motor mounts(possibly?), cross member(possibly?)

Of course I want to be as cost efficient as possible.

Looking forward to your responses.

I have noticed but they all seem to have scattered answers so was just looking for more direct answers.

Insurance auto auction, buy a running and driving donor vehicle. Look for those that weren't rolled or front crashed. Rolled could indicate the engine may have ran with no oil upside down for a period of time, front crash could indicate it ran without coolant for a period of time. Park donor vehicle beside your truck and start swapping parts.

biggest thing you would need to check is the oil pan clearance. might be a different design than the 4.7, also with the correct motor mounts it should drop right in
