In the midst of the Z06’s development, engineers knew that something truly remarkable would be needed to best the base Corvette’s 400 horsepower LS2. In its production form, this new small-block V8 came to be known as the LS7. The LS7 was nothing short of all-powerful, featuring a displacement of 427 cubic inches and an output of 505 horsepower.
In 2013, a revelation of sorts took place within the Corvette world. General Motors unveiled a “best of both worlds'' type offering, which paired the C6 Corvette, in its convertible form, with an indisputably fearsome powerplant. Beneath the Corvette’s hood, sat a 427 cubic-inch small-block, which carried the LS7 designation.
