83 F350 engine swap

I have an 83 F350 with a junk carb'd 351. I also have an EFI 351 out of a 97 F250 that I want to put in it. I am looking for help on the details of this swap.
Do I need to change distributor gears?
Will the eccentric bolt right on or do I need to change the timing set?
Are the motors balanced the same so I can reuse my clutch/flywheel?
Are the water pumps the same or do I need to use the old one?
Any other details I may be missing?
I need to be able to do this in a weekend so I can get it back out of the shop.
Thanks in advance for any help.

Do I need to change distributor gears?
I didn't on the 302 FI swap I did, and it worked fine.

Will the eccentric bolt right on or do I need to change the timing set?
It bolted right on my 302 swap, the 351w should be no different.

Are the motors balanced the same so I can reuse my clutch/flywheel?
351w never changed their balance like the 302 did.

Are the water pumps the same or do I need to use the old one?
The waterpump should be different because the old engine was a v-belt setup and the new engine is a serpentine setup, so the waterpump and fan turn backwards. Use the timing cover, waterpump, v-belt pullies, etc. off the old engine. When I swapped timing covers on my 302, I had to drill the dowel alignment holes out to 1/2", but then it fit fine, and let me use a regular fuel pump.

When I swapped the carb manifold on the later 302, the gasket set I had gave me two different intake gaskets. I scratched my head a little bit and found the later intake gaskets were the ones to use in my swap.
