'01 Mallett/Cartek Z06
At what point does a small-block officially cease to be "small"? Thanks to the LS-engine experts at Garwood, New Jersey's Cartek Racing (www.cartek.net), the answer is "a lot bigger than you might think." To create a properly puissant engine for Helmintoller's '01 Mallett Z06, Cartek's Dave Busch and Julio Hormilla wedded a re-sleeved LS6 aluminum block with a 4.125-inch forged Lunati crankshaft. The result is a 436-cube colossus worth a dyno-verified 532 rear-wheel (around 625 flywheel) horsepower. (The total may actually be higher now, as Helmintoller has added a Meziere electric water pump and a freer-flowing 3-inch exhaust system since the car was last dyno'd.)
Unlike the virginal '06 Z, the '01 was a dragstrip veteran that had been painstakingly annealed for the rigors of all-out acceleration testing. We weren't too surprised, then, when the car promptly laid down a string of low 11s at 126-128 mph, easily bettering the efforts of its current-generation competitor. Mickey Thompson slicks and a race-spec clutch meant the C5 Z could be launched much harder without fear of scrambling driveline parts, and a short-throw B&M shifter made executing rifle-shot Two-to-Three shifts a considerably less nerve-jangling affair.
