Sixteen Power debuted their 14.0 L V16 engine at the Miami Boat Show 2017. The engine is based on the GM LSx platform and is essentially two 7.0 L LS7 V8 mated together in a single block. It retains a 4.125-inch bore and 4.000-inch stroke and will accept aftermarket LSx heads and intake manifolds. The engine will be offered in 900 HP, 1200 HP and 1400 HP naturally aspirated versions and 1,600 HP supercharged and 2,000 HP quad-turbo versions coming. Sixteen Power designed the engine for boats but I have to believe someone with deep pockets is already dreaming about installing one of these in their vehicle.

If I’d have the cash I’d put 2000 hp quad turbo version into a Silverado

That would be a wild combo. I hope someone actually purchases the quad-turbo version. I need to see and hear that.

I can see it making its way to Bonneville. With even more power

I believe Chevrolet had shoehorned a Caddy V16 before in a Tahoe, which later on was used in the Cadillac Sixteen. Though that might not be factual as I don’t have the photos.

Now someone can now build their own Cadillac Sixteen.

You are correct in your memory. They did indeed shoe horn a V16 Northstat based motor in a Taho test mule. There are published stories. It was later installed in the Cadillac Evoc, Super sedan, With a very knife edged Design. It was a Design study for a Flagship automobile, to compete with the top touring sedans of the world. It was as Shiny Black as Obsidian, and just as sharp, design wise.
