Motor adapter plates
figuring out your LT1 trans to an LSx trans or replace it with an LS trans.
caps lock off
a tune
I am not sure about the LT1 fuel pump, it may or may not be enough to hit the 58 PSI needed at the rail. I don't know what stock LT1 fuel pressure is.

FEAD is Front End Acessory Drive.

i.e. truck, GTO, F-body and Vette
Get a intank Walbro pump from any of the performance suppliers and a '99 vette fuel filter/regulator.

I have a set of laser cut engine mounts in the work that'd simplify installation in my 96 9c1 and my business partner 94 9c1. Will advise on fitment in the next week or so.

I actually switched from the Truck FEAD to the Camaro FEAD with a L92 water pump afte a while. I used spacers to space everything out 3/4".

Yes, you can keep the 700r4, you will just have to buy the spacer and bolts for the flexplate. Controlling it is another story though.

As long as your trans is a non 'E' model or not controlled by the engine computer, I don't see why a early 4L60 (700R-4) wouldn't work behind a drive by cable style LSx engine.
