Details and Performance Options
We all know that it's the careful selection and execution of details that make or break a car. Your KKC Stingray can be tailored with custom wheel-and-tire combinations, headers and exhaust systems, and even big-brake upgrades. Hidy says Z06 brakes are among the most popular upgrades currently.

As you might expect, there's a quarter-mile-long list of engine options available at Karl Kustom. Most notably for those customers wanting to go all-out, the new Lingenfelter Performance Engineering Z067 has just been announced (see sidebar).

Another popular choice is the Edelbrock E-Force Supercharger Kit. The basis for this system is an Eaton Gen VI 2300 TVS supercharger rotating assembly, similar to the one employed on the ZR1. The Edelbrock kit provides instant, reliable, and safe horsepower with a low boost level to minimize stress on the engine. A typical installation will take an otherwise stock LS3 engine up to 599 hp, or an LS7 to more than 650. This package can be added for approximately $9,700.

Making It Happen
Karl Kustom Corvettes is affiliated with Karl Chevrolet in Ankeny, Iowa, one of largest Corvette dealers in the country. This allows the firm to easily source exactly the right new car or locate a pristine, low-mileage used Corvette for modification for its clients.

Approximately 50 Karl Kustom conversions have been completed to date, and each car sports a serialized badge between the seats. A conversion on a standard C6 starts at $90,000, while a Z06 or Grand Sport adds an additional $5,000 to the total. ZR1 pricing is expected to be near $100,000. Start to finish, a Karl Kustom conversion takes 8-10 weeks to complete.

According to Hidy, the bottom line is this: "We will build anything our clients request. Want a '67 big-block ‘stinger' hood on a '63 split-window with a '67-style backup light? No problem—we're happy to do it!"

The Karl Kustom/LPE Z067
KKC and Lingenfelter Performance Engineering (LPE) have recently teamed up to build what may be the ultimate midyear conversion: the Z067. Based on a C6 Z06, the car's LS7 undergoes massive upgrades, including ported and polished heads, a hotter cam, an enhanced induction system with upgraded fuel injectors, and myriad other components.

When installed under the hood of a KKC Stingray, this 660-horspower, naturally aspirated monster is a Corvette like no other. Turnkey pricing, including a suitable car, starts at $165,000.

The LPE 660HP 427 package includes the following:

  • Engine removal, including removal of the intake manifold, cylinder heads, and camshaft
  • LPE CNC porting and polishing of cylinder heads for optimal flow
  • LPE multi-angle valve job and surfacing for 11.5:1 compression
