Gen III X-tasy
Do you want the reliability of a solid roller on your LS1, LS6, or LS2 street car? COMP Cams' XFI Solid Roller Gen III cams bridge the gap between lopey streetable hydraulic setups and race-only custom-grind solid rollers. This new line offers the most aggressive lobe profiles, specifically designed for street cars to yield massive increases in power output, throttle response, and high-rpm capability. Three grinds are available to meet different rpm ranges, from the modest 235/240 duration, .646/.641-inch lift XFI2700113 cam, to the lumpy 251/256 duration, .660/.655-inch lift XFI286R113 bumpstick made to buzz to 7,000 rpm; the middle-of-the-road XFI278R113 still peaks around 6,700 rpm, with 243/248 duration, .653/.648-inch lift. All cams carry a 113 lobe separation angle, and are designed for use with high-flowing heads and intake such as the LSX.

Rock 'n' Roll
Want to rock your Gen III's valvetrain like a hurricane? Check out Scorpion's LS1/LS6 Roller Rocker Arms for bolt-on horsepower without changing pushrods, guideplates, rocker studs, or valve covers. These anodized and laser-etched aluminum rockers will significantly reduce valvetrain weight, to enable faster valve actuation and more power. Scorpion is known for producing some of the best SBC and BBC rockers money can buy-and now the LS1/LS6 motor can be added to the list. Both the stock 1.7 and 1.8 ratios are available.
