Holden's engine cover doesn't lie. The 'L' may be chopped off in the photo, but that's clearly an LS7 7.0 Liter.

Yes, we realize that Top Gear Australia has been cancelled, and yes, this video is over a year old. Having said that, this one has somehow slipped through the cracks over here at LSXMag, a website that always brings you the latest and greatest information in the world of everything LS-powered. Unless we miss it when it’s first posted…

Over the last several months, we’ve been greatly anticipating (with great excitement) the unveiling of the 2014 Chevy SS sedan. An essential replacement to the departed Pontiac G8, the upcoming SS sedan will be packing LT1 power and a complete update over the old Pontiac.

But somewhere between the Pontiac getting the ax and Chevrolet developing the new SS, Holden released the Commodore HSV W427. It’s basically a hyper-souped up version of the regular Commodore SS that served as a basis for the G8 GT. Except that “427” numeral isn’t call out for the amount of horsepower under the hood – it’s the cubic inches!

Yup, rather than relying on a 430 HP LS3, this car is packing the same 7-liter LS7 that the coveted Corvette Z06 does. We find this rather contradictory and not exactly surprising to a recent story we ran last week when Ken Lingenfelter went on record saying that an LS7 Camaro could never happen.

As everyone knows, the Beta platform found underneath the Commodore/Caprice/G8 is the same one used in the current Camaro. Ken cited that not only does the Z06’s dry sump oil reservoir not fit under the hood, the LS7’s exhaust manifolds will not fit between the frame rails. We would assume that if that were even the case, the LSA/LS3 exhaust manifold would just as easily bolt to the engine and thus, fit inside the car. But what do we know? We’re just automotive writers.
