Blue Devil V12 Engine

I was watching a documentary on the latest Ferrari V12 which has a 90 degree V, unlike most V6 and V12's that use 60 degrees. That is because a V12 is basically two straight I6 engines and an I6 engine is perfectly balanced, meaning you can use any degree V banking you like.

So why not splice 4 extra cylinders into the middle of an LS7 and make a 750hp 666ci (the devils own number ) V12?

A great engine for a Super ‘Vette, which can also be used detuned to say 600hp for smooth and powerful Cadillac.
