Video: Lingenfelter Shows Off 427-Powered E-Ray on the Dyno
Lingenfelter Performance has been churning out performance packages for GM cars, trucks, and SUVs for decades, and its latest engine options for the mid-engine C8 Corvette have a nostalgic ring to them. By giving the LT2 V-8 in the Stingray new sleeves, a 4.0-inch Callies crank, and 4.125-inch Mahle pistons, the former 376-cubic-inch V-8 is transformed into a 427 like a modern-day LS7. The new short-block teams up with CNC-ported LT2 heads and a custom-ground camshaft to produce 700 naturally aspirated horsepower at the crank. A carbon-fiber intake, as shown above, is optional.
Although the Eliminator Spec S engine package, as Lingenfelter calls it, isn’t new—we reported on the engine’s availability in the Stingray shortly after it was revealed early last year—this chassis dyno video is. The big-inch small-block adds 138 hp and 100 lb-ft of torque to the rear wheels and sounds great doing it. The car on the dyno, however, isn’t a Stingray, it’s an E-Ray. Lingenfelter initially advertised the Eliminator Spec S engine package for LT2-powered C8s, but didn’t explicitly say that included the hybrid E-Ray. A few months later, the company cleared that up and mentioned that the AWD Vette was available to receive the $30,000 engine upgrade, but this is the first time we’ve seen one in action. We can only imagine how the combined 860 horsepower from the 427-powered E-Ray would rocket the C8 around a track. Considering the 427 produces more power than the LT2 at every point in its rev range, it sounds like there’s not much downside.
Lingenfelter did a lot of development to ensure that the new rotating assembly works with the LT2’s dry-sump system and designed its custom cam, ground by Comp Cams, to work with the C8’s eight-speed Tremec DCT. We can only assume that getting the powertrain to work with the E-Ray’s hybrid drivetrain was a unique challenge. Still, it proves that even high-tech, high-powered sports cars can leave someting on the table for the aftermarket.

Dyno was neat to watch but I want to hear this thing in anger on the track, startup, etc.
