Katech Street Attack 500 Crate Motor
At 600 hp, the Street Attack 500 was designed by Katech to be one of the most powerful emissions-legal, naturally aspirated motors on the market. Using the new Dart billet 6061-T6 aluminum blocks to allow a lengthy 4.500-inch stroke, the Street Attack boasts a very un-small-block 500 cubic inches. Liner-less, Nicom-coated bores reduce friction and improve heat transfer with the all-forged rotating assembly. The top end is all LS7 from the valvetrain to the heads. The intake also lends to the motor's awesome potential, which carries a 12-month, 12,000-mile warranty. Expect 500-cube versions of Katech's other packages such as the Desert Attack to be available soon as well.
Granatelli Motor Sports Dual Window Switch
GMS's new Dual Window Switch is innovative in its flexibility of use. Users have the capability of controlling two stages of nitrous; or one stage and a shift light, water, or methanol injection; or even a high- or low-voltage tachometer. You don't even need a tach input, as a fuel injector wire reading easily takes its place. It's able to drive an external tach and read a 0-12-volt throttle position sensor (TPS) signal (or 0-to-5), yet it still functions quite well as a simple window switch for nitrous activation from 1,000 to 15,000 rpm.

A custom 3.5-inch aluminum radiator and two SPAL fans not only handle cooling, but also give added clearance for the piping and 3-inch bar and plate air-to-air intercooler. Oil drain and feed lines are also included, and this kit maintains stock A/C, as well as the accessory locations. Turbo, downpipe, and air-to-water intercooler upgrades are available. An LT1 kit is also now available. Both cost just under $6,300 (everything included) for the base kit.
