Lingenfelter LT2 427 Stroker Debuts With 700 Naturally-Aspirated Horsepower

The number “427” is one that holds a special place in the hearts of GM fans, whether that stems from its early days as a big block or the more modern engine of the same displacement. However, the debut of the C8 Corvette meant the arrival of a new powerplant – the 6.2-liter LT2 V8 – which is used in the Stingray and the E-Ray, the latter of which mates it with an electric motor as well. That means the aftermarket was sent back to the drawing board to figure out ways to extract more power out of the heavily revised mill, and the latest fruit of that effort is the new Lingenfelter LT2 stroker, which displaces 427 cubic inches, too.

This impressively punched out Lingenfelter LT2 was revealed by the company itself recently, but at that time, it didn’t give us much information, save for the fact that it made over 700 horsepower and 600 pound-feet of torque on 91 octane fuel – truly impressive figures by any measure. However, MotorTrend was able to get more details on this exciting new powerplant, shedding some light on how the longtime Corvette tuner managed to accomplish such a feat.
