And finally, Lunati has expanded its line of Voodoo aluminum roller rocker arms into the LSx family. They are constructed from high-quality aircraft-grade aluminum and have extra-large trunions and bearings to provide greater power increases and greater durability. They'll clear spring diameters as wide as 1.650 inches to provide space for large aftermarket springs. And if that's not enough, they're anodized black with a laser-etched Voodoo logo.

Development of components for traditional small- and big-blocks has been limited compared to the LS line, but Lunati is still at work filling out the traditional engine line. In fact, camshaft engineer Harold Brookshire, who started the Voodoo line, has rejoined Lunati to complete the line. So you can certainly expect more to come.

There's also the Bare Bones line, which is a less expensive alternative for the 75-80 percent of people who just want a cam. "We still want to make sure the customer who wants a little power and sound is covered. But the premium line is still the Voodoo." As for valvetrain, Lunati has been hard at work there filling its valvetrain lineup, including a complete line of Pro Series pushrods along with more keepers, retainers, and springs, all with an eye toward bringing the company into the 21st century.

"We're in the mode of constantly developing now," Humphrey summed up. "We're back in the game to develop, and especially to work with racers. But the bottom line is that if we don't have it, we can do it. We've definitely got it covered, and we know we're not gonna stop finding people doing entirely different things." About this direction, Humphrey says, "This motor's not going away. It's here to stay. It's just so easy to make power."

Truth be told, we didn't really know what to expect when we entered the world of today's camshaft and valvetrain tech. The level of innovation and the ever-increasing performance of the products being are impressive, to say the least. The number of new cams being produced is mind-boggling-pick your powerband, pick your power level, and somebody's already producing the perfect cam for you. And now we've got 'sticks to work with previously exotic technologies like variable valve timing and displacement on demand. The future looks bright, and we can hardly wait to see what these guys come up with next.
