Do some reading in the LS1 Swap FAQ thread stickied at the top of this directory, should get you started.

You need other stuff. Fuel pump and plumbing, cooling fan(s), engine mounts, air intake ducting and filtration among other things.

You also need to get 12VDC to the right places on the LS1 harness, get some gauge outputs from the right places on the harness, relay the fuel pump and fan(s).

You need to get the PCU tuned to eliminate VATS or get a VATS simulator. You can build one for a couple of bucks. There is a schematic posted in this forum somewhere.
