Dodging cones and rainstorms in Norwalk, Ohio, during the inaugural Lingenfelter Performance Nationals, Dave Michaels captured the Grand Champion award for the OPTIMA Challenge qualifying competition driving a Thomson-powered Corvette Grand Sport. With upgraded brakes and some additional safety equipment, Michaels channeled the power of more than 700 naturally aspirated horsepower from our new 442-cubic-inch (7.2 liters) LS7 engine package. Michaels not only ran away with the quickest time on the autocross course, but delivered a great quarter-mile ET of 11.38.

We've built a number of these great 442-inch LS7s for other racers and can give the same edge on the track with one. Call us at 248-349-0044 - and we’ll build a 442 LS7 for your street or race car!
