Ewanitsko made two starts in the NASCAR Craftsman Truck Series whilst driving for Long Island Motorsports, finishing 21st at Watkins Glen International in 1997, and 35th at New Hampshire Motor Speedway in 1998.
Ewanitsko found the majority of his success in the NASCAR Whelen Modified Tour, where he scored 28 wins and 21 pole positions, and finished runner-up in the standings in 1998 and 1999.
He started having problems with his vision during the 2000 Modified Tour season, having developed cataracts in each eye.
Ewanitsko then underwent surgery to repair the cataracts a few years after, and made a brief return to the series in 2005, where he finished fourth at New Hampshire Motor Speedway whilst driving a car for Eddie Whelan.
After finishing 32nd at the season finale at Thompson Speedway, he fully retired from competition due to complications from his diabetes.
