Was browsing thru the topgear article and images:

And saw that the new crank actually has a keyway on it now So glad they added this feature. The LS cranks sucked in this area for those of us who added forced induction.

Thanks GM

Seems like this engine was meant for FI from the jump. Won't doubt the next version in the family being FI.

Well, except for the 11.5:1 compression, yeah- looks like this engine would be good for FI LOL Nothing a different piston couldnt change tho

Why change the pistons? With DI, and piston oil squirters and running a lower boost, 11.5:1 CR is okay, as long as it isn't tuned on the ragged edge(which GM isn't going to do).

The LS7 has 11:1 CR without the cooling benefits of DI or the piston oil squirters, and an E-Force at 5.5 psi boost has 657 horsepower.

ChevyChad

Good points... but who wants low boost?
