Tired of all the gloating from the middle-aged and balding men who pre-ordered a C6 ZR1?  Techco has an answer for you.

The Anaheim tuner, which has experience working with Mopars and Saleens, is offering a large-displacement blower (three liters in all) and a dual “AFrame” intercool system as part of an $8,500 performance package.

I know…eight grand isn’t cheap, but it is a bargain when you see the numbers: horsepower from Chevy’s LS3 V-8 is increased by 40% to 600 and torque is pushed up 11% to 535 ft-lbs.  That goes for the LS3, but the upgrade can be hooked to any C6 engine (LS2 and LS7) without any exterior adjustment to the hood.

If you could call one ‘Vette a sleeper, this’d be it.
