Vortec to LT-1 Swap

Thinking about swapping to an LT-1 from the 5.7l Vortec I have in my 98.

Anyone attempted or done this before?

I know the wiring harness and ecm are must swaps, but anything else I should know?

Fuel pressure IS different, the fuel pump from your LT1 donor vehicle should "bolt up" in to your sending unit and provide adequate fuel pressure.
