Katech Inc.
Well known for both racing and high-performance street engines, Katech is one of the most respected names when it comes to Gen III and IV motors. The company has proven itself time and again since it first became involved with the Corvette C5R factory racing team, and its line of performance street engines is a natural offshoot from this success. As we've hinted, several different LS7 packages are available (depending on your intended application), so be sure to have a look at the company Web site (www.katechengines.com) for more detailed information.
