Initially planning to run full-time in the Nationwide Series, in 2010 Conway signed to drive the No. 37 ExtenZe Ford in the Sprint Cup Series for Front Row Motorsports as a teammate to Travis Kvapil and David Gilliland. Conway's lack of superspeedway experience caused him to delay his Rookie of the Year campaign, as NASCAR would not give him approval to compete in the Daytona 500. Kvapil raced the 37 at Daytona, while John Andretti ran Kvapil's 34 car. Conway earned a career best finish of 14th at Daytona International Speedway in July, one of only 3 finishes better than 30th in 2010. As the only fully sponsored driver in the Front Row stable, he rotated among the team's No. 34, No. 37, and No. 38 cars in order to remain in a Top 35-ranked car that would guarantee a starting spot. Prior to the August race at Michigan, Conway and the ExtenZe sponsor logos were removed from the car, with Tony Raines replacing him. Conway and ExtenZe would go on to be sued by Front Row Motorsports for lack of payment, which they cited as the reason Conway was removed from the car.
