I like that HSV having a bigger engine over Holden that gives it more cred and people more reason to buy something more high performence.
Like a Guy that owns a VZ Monaro could turn to a guy that own a Club R8 in VYI and have a big smile on his face same engine same power, Just the monaro has twin pipes that look good out the rear, Now HSV owners have something over holdens drivers which is the way it should be.
So Holden with 6.0lt and HSV with 6.2lt would be right It also keeps the power up over holden

Now buying a Clubsport with GEN4 at $60,000 is a great buy. And it gives you thoughts when you buy a VZ SS $51,000 it's only $9,000 more for the Clubbie
Read up on the GEN4 it's got great low down power just off idel, And it holds it's torque very well through the rev range, This engine is probley faster then the C4B
HSV have claimed 5.1sec that's better the GTS
