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

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

Watch the video... it shows the engine. An LS motor. What's funny, they talk about getting the C5 Z06 and it being the last and best of the C5's but talk about it having a "ZR-1" motor. (I think they're confused.) But that's not what's in the photos and film they show. It's an LS motor, coils on the valve covers and everything.
