Johnny's draw to the innate challenge of Pro Stock racing reached a new level in September of 2009, when Gray Motorsports laid the groundwork for a fully equipped 24,000 square-foot race shop with one goal in mind: to develop a top of the line in-house engine program capable of winning NHRA Pro Stock world championships. The following season, Johnny made it a family affair and launched a two-car team with son Shane joining the fold and making his debut at the season-opening NHRA Winternationals in Pomona.

Gray Motorsports was soon turning heads as the father/son duo made a collective four final rounds and ended their inaugural year as a team with Shane's first national event win, which he earned at the NHRA Finals. Notably, Johnny and Shane each earned a coveted spot in NHRA's series playoffs, known as the Countdown to the Championship.

When Johnny returned to the seat of a Funny Car in 2011, Shane continued to carry the banner for Gray Motorsports in Pro Stock, collecting experience and establishing a quiet yet powerful presence. Shane enjoyed a career year in 2013 as he reached an impressive six final rounds and narrowly missed nabbing the No. 1 qualifier position at three separate events.

Inching ever closer to the level of success that the Gray Motorsports team was designed for, Gray Motorsports made a monster move in the world of Pro Stock at the conclusion of the 2013 season. Gray Motorsports and Cagnazzi Racing merged their solidified groups to create a super-team with the driving crew expanding to include ever-threatening multi-class competitor Dave Connolly. Behind the scenes, Gray Motorsports incorporated a powerful group of experienced personnel that would quickly come to complement the sturdy framework already in place. In 2014, Johnny's youngest son Jonathan joined the team as the third Gray Motorsports Pro Stock driver. Come 2017, Shane's son Tanner took over the driving duties in the full-time ride.  Tanner won in just his fourth start, becoming the youngest NHRA driver in history to win a national event at the age of seventeen. By the end of the season, Tanner collected five wins, finished fourth in the points standings and was named the Auto Club of Southern California Road to the Future Award Winner. 

Gray Motorsports possesses an impressive total of 22 NHRA national race victories, 15 of which were earned in what is arguably the most competitive category in NHRA drag racing. At the heart of Gray Motorsports is the goal of delivering race wins and championships through the utilization of cutting edge technology and proven methods.
