Ahh you are tossing a 3.4 into a 3rd gen?? Easy man. All you have to do is toss it in. Change a few wires for the ignition to be dis. Change the tune which I can help you with. And you are done. It's quite simple. But I would recommend making it a hybrid top end and ditching the sfi injection .

This write up I did should help. Remember hybrid swap or not. A 3.4l swap into a thirdgen is the same minus the little things such as a throttle cable or t stat housing. Look at the dis ignition wiring in the write up as it will be the same weather it's a hybrid swap or 3.4 swap.
