4l80e and LS2 Crate Motor Help

[InMotionJosh]

I am about ready to order my drivetrain for my 70 Chevelle Project but need some help with a few things. I used an iron block 6.0 out of a HD 2500 Truck that was backed with a 4l80e. I plan to keep the 80e and bolt it to a crate ls2. The LS2 description says it comes with a flywheel for an automatic transmission but what else will I need? I plan to buy a new converter but am not sure what else ill need to make it work.
