Default 94 LT1 into a 97. what all needs to be swapped?

so i was going to post up my firebird for sale for dirt cheap (3g's) because i have too much going on and dont need 2 fbody's. But my buddy had the genius idea of wanting to just buy my motor for $2500 and giving me his stock motor along with the cash. The question im having is what all do i need to swap over between the 2 motors? i kind of have a general idea but its always nice to double check. so lets here some input guys!

You will need to use the 97 timing cover,opti and harness, cam, crank sensor swap a few fittings over in the intake to allow the vented opti and thats it.

What about the reluctor ring for crank sensor? I am doing the same swap. Will it fit on 94 crank? Do you just need to change the crank key?

Yes, however, you need to swap the hub too.....OBDII hubs crank hubs are a little shorter IOT fit the reluctor and maintain belt alignment

Would it still fire up and run even if you decided to leave the 94' timing cover and components on.
