Stew Ingalls' LT-1 powered '87 T-II

I have an LT1/4L60E in my 87 TurboII that I have enjoyed for the last few years , using your kit, but now I have a line on on 05 LS2/4L60E from a GTO.
I understand the oil pan might not fit. Do you know if that is true? Do you know if the exhaust manifolds would work. Thanks for any help.
Here are a few pics of my current car. Ran 12.6 at 109.75 closed exhaust & drag radials.
