70 Firebird Formula LS engine swap

[sr671]

Hi guys, I'm new here so please bear with me as I'm sure this is stuff that has all been rehashed on this site many times before. I have sean differeing stories on puting an LS into a 2nd Gen F-body. I've had many different engines in my firebird over the years, and the last one was a small block Chev, and those are the towers currently installed on the crossmember. They are the short wide towers. The engine is in the same location as if it were a 70-72 Camaro. Does anybody know if you can bolt an LS in without cutting the crossmember and moving the engine if useing a 2000 Camro pan? I would not be totally adverse to moving the engine back if neccesary. If so which mount has been used. I have access to a set of LS conversion plates that use the Energy short wide mount.

If anyone out there can point me to a detailed 2nd Gen LS swap I would appreciate it.
