Best way to buy the lt1 engine is with engine wiring harness and pcm. That way half the battle is over. Even though the 94 used the electronic computer controlled 4L60E trans, converting to the 700r4 would simply mean tuning the 4L60E functions out of the pcm.
You would also need the throttle body and TV cable from a 92 or 93 lt1 engine. This will make swap easier for you. BUT using a 94 4L60E, would make the swap even easier.
Look on craigslist for engine wiring harness & pcm. You can use the 94 z28, formula, or trans am harness & computer also.
And welcome to the forum.
