Lately, we’ve been bringing you TONS of insanely awesome swap stories; from an LS7-powered Porsche 911, to the mid-engined, twin-turbo LSx ’37 Ford coupe. The popularity of the LS series engines continues to grow, and your author still remembers a time when the only cars running them were C5 Corvettes and the ’98-02 4th-generation F-bodies. Times have clearly changed and we’re not mad about it at all. We’ll keep them coming as long as you guys keep building them.

However, it isn’t just the Frankenstein swaps that we are seeing. Enthusiasts everywhere are still quite fond of the cars the LSx engines were born with, and we recently heard the tale of one first-generation CTS-V owner who is currently in the process of removing the LS2 from his Cadillac, and is replacing it with an RHS 429ci-stroker.

We caught wind of this story from Rick LeBlanc of Livernois Motorsports, who will be handling the build. The fortified aluminum stroker block will be stuffed with a Livernois forged steel crankshaft and 11:1 compression forged pistons, and complimented by their own H-beam connecting rods with ARP 2000 bolts.

Here's the 429ci. RHS block in question. It will be replacing the stock 400HP LS2 mill that initially powered this customer's V.

Livernois will also be tossing in coated bearings, rings, locks, and wrist pins of their own design, a Stage 2R Max camshaft, and the CNC-ported LSX/LS7 cylinder heads. They’ll also be sprinkling in a set of Comp Cams short travel race hydraulic roller lifters, ARP studs, and a Melling oil pump will be responsible for lubricating duties.

Inhaling oxygen will be a custom cold-air intake, while expelling the spent gases will be a set of Kooks long-tube headers and mid-pipe with catalytic converters and a Corsa exhaust system.

The stock T56 trans will be getting many upgrades, including an LS9 clutch and an aftermarket aluminum flywheel. Since your author is also an owner of a CTS-V very similar to this one, I can attest to the fact that the factory shifter unit is sub-par, and that will be getting replaced as well.

I can also mention that the V’s factory suspension, though very impressive, can use some improvements as well, and that’s just what’s in store for this example. So while it’s under the knife, it will get new coil-overs, sway bars, tie rods, and trailing arms. Out back, the new 429ci LS will turn a 9-inch differential (blasphemy!) with 35-spline axles.

In an interesting twist to the story, the owner of this particular V  has yet to see the car in person himself since he just purchased it secondhand over the internet and had it shipped directly to Livernois for all the upgrades. Why waste time driving a stock car, right?

We’ll continue to monitor the build on this CTS-V, and once it’s completed, we’ll be happy to bring you an update on this story when the time comes. Having said that, it’s managing to inspire us to build our own Power Automedia CTS-V to same the same degree.
