LSx Based 14.0 L V16

Sixteen Power LSx based 14.0 L V16

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.
