Yes. It will not run with vats enabled.

Re: 5.3 conversion????
Definitely need the vats removed. If you don't want it spitting codes, it should have the downstream O2's and emissions diabled. I use Brendan from LT1swaps.com for PCM work.

You'll also have some cross member / framing work to make it fit, driveshaft, etc.

Re: 5.3 conversion????
Sure, you could do that.
If you aren't planning to run all 4 oxygen sensors, an evap can & catalytic converters, though, you'll need an ECM flash to keep from spewing trouble codes. If you're getting an ECM flash, just ask them to remove VATS at the same time.
