Re: 1998 Chevy BBC 454 Vortec motor and 4L80E trans question
If you aren't planning on modifying the engine you could have the factory pcm flashed to get rid of the vats, but it can also be flashed later if you want to add a cam, etc. For the most part you could make it plug & play, you would send your pcm and wiring to a place that specializes in retrofits, they modify the harness for battery power/ground/etc. and it makes it a bit simpler, but you need a high pressure pump for port injection.
