That's too bad about the engines getting stolen. I am still leaning towards the LS, FI is nice and since they're everywhere. I can see myself doing a couple more engine swaps in the future and I think if all of my projects are the same engine it will be a little easier in the long run. For now I'll keep the same chassis, I was just thinking it might be easier to set the cab on a 2000s suburban chassis and call it good, but maybe it isn't all that simple.
