RE: what to know about an ls1
The TH350 trans will bolt up to a LS1. But you will need a complete wire harness, computor and all sensors and accesoriesfor the LS1 to work. There is a Painless harness that will work as well. You can also carburate the LS1, there are kits out there to do it, but it would probably cost more or be equal to going fuel injected.
