Jimmy Prock is among the most renowned crew chiefs in the sport today. The tuner of the Infinite Hero Dodge Charger driven by Jack Beckman has a career total of 71 wins and two championships.

Prock began turning wrenches on father Tom’s Funny Car at a very young age and worked for Tom McEwen, John Martin, Connie Kalitta, and Dick LaHaie before receiving his call up to the crew chief position for Cory McClenathan late in the 1991 season at 25 years old.

Prock came within a round of winning the 1992 championship with McClenathan despite missing the Montreal event that year due to financial constraints. He went to work for Joe Amato in 1994 and won a total of 21 events as a Top Fuel crew chief before he moved to Funny Car in 2001.

Prock was assigned to John Force Racing’s experimental Funny Car driven by Gary Densham where he developed his high-horsepower Top Fuel engine tune-up for the Funny Car application for it to be adopted by the other teams. Prock won eight times with Densham, including a double-up at Indy and the Skoal Showdown special event in 2004, before Robert Hight took control of the Auto Club entry in 2005. He tuned Hight to the 2009 Mello Yello title and 27 event wins before being reassigned to John Force’s team. With Force, he won eight races and the 2013 Mello Yello championship.

Prock went to work for Don Schumacher Racing at the end of the 2014 season and revolutionized the category during the 2015 season with the performance of the Infinite Hero Dodge Charger. Prock popularized laid-back headers when he lowered the national e.t. record four times beginning at the Sonoma event. Beckman scored seven wins and finished No. 2 in the Mello Yello standings.
