That's why they call it 490?

Yep!
Like your ZR-1 GM rated at 375hp!
This is why they are so generous with the dyno sheets.

If you watch the video, you'll see it's an LS6. The donor chassis was a C5 Z06. Cool, but not powered by and LT5.

OK I am almost certain the original version of this came with an LT-5.....maybe it was just in the concept drawing. Will look through the 100 or so mags I have, I know its in there

The article said zr1 and so did the subtitles, but when watching it, I saw the ls intake, hence my edit. Would have been way cooler with an LT5.

Cool build, but yes that doesn't even come close to sounding like a LT5..

So there is a ZR-1 tie to the ISO, the ZR-1 was to be the platform for the ISO when it was originally built, in fact they bought a test mule Z to build it....and apparently maybe had one built and that Z is now MIA.
