Huffman began his racing career at Hickory Motor Speedway in late model stock car racing. In 1996, he won the Late Limited Model Series championship. In 1999 he won the late model track championship, the Blue Ridge Regional Championship, and was the runner-up for the NASCAR Winston Racing Series Champion. In 2000, he moved up to the USAR Hooters Pro Cup. After posting no top-ten finishes in his rookie year on the circuit, he won his first career race at Coastal Plains Speedway in 2001. That same season, he made his NASCAR Busch Series debut at Richmond, driving the No. 77 Jennie-OFord Taurus for Moy Racing. He started 40th and finished 24th, three laps down. After a winless 2002, Huffman won five races and was both the champion of USAR's national points standings, as well as the Southern Division. He repeated his Southern Division title in 2005. Huffman has 28 wins in 133 starts in USAR – the 2nd most wins in the USAR series history. Huffman holds the record with most poles in USAR history at 26. Huffman had three wins in USAR in 2006 driving the No. 88 Champion Chevy for JR Motorsports. He made his first Busch start that year driving the No. 83 Make-A-Wish Foundation Chevy for at Gateway International Raceway in a JR Motorsports car prepared by NEMCO Motorsports. Following the release of regular 88 driver Mark McFarland, Huffman shared the driving duties of the 88 for the rest of the season with Robby Gordon and Martin Truex Jr.. He started the 2007 Busch season in the No. 88 car. On July 3, 2007, Dale Earnhardt Jr. released Huffman from driving the No. 88 Navy Chevy for JR Motorsports. He went on to compete part-time in the Truck Series with Curtis Key Motorsports in 2007. Huffman returned to Nationwide racing on July 4, 2008, driving the No. 31 car for Stanton Barrett Motorsports in the Winn-Dixie 250 at Daytona International Speedway. He started 21st and was able to lead 2 laps when he remained on the track after a lap 14 caution caused by the spinning No. 22 car driven by Josh Wise. When the green flag dropped on lap 17 Huffman was able to hold off a charge by his ex-boss, Dale Earnhardt Jr. After 2 laps he was passed by Earnhardt and remained in the top 10 for one more lap before falling back in the pack. Huffman eventually finished in 41st position, 82 laps down.
Crew chiefing career
After he was released from his ride with JR Motorsports midway through the 2007 season, Huffman joined Rusty Wallace Racing as a car chief for Steve Wallace before moving to the Truck Series. In 2014, he was the crew chief for Brandon Jones at Turner Scott Motorsports in his full-time ride in the K&N Pro Series East as well as his part-time rides in the Truck and ARCA Series. At the very end of the year, he and Jones joined GMS Racing when Jones' No. 33 team was sold by TSM due to the team's financial problems. He continued to work as crew chief of the No. 33 truck when it became full-time in 2015 with Jones and the Dillon brothers until his suspension from the final two Truck races, where he subsequently left the team entirely. The following year, Huffman returned from his suspension and joined Red Horse Racing where he crew chiefed Timothy Peters' No. 17 truck. In 2017, Huffman moved to MDM Motorsports and their No. 99 truck, where he reunited with Jones and the Dillons and later Peters too. The other drivers in the truck that he got to crew chief that year were Tommy Joe Martins, Travis Miller, Bubba Wallace, Brian Wong, Cale Gale, and Dalton Sargeant. On August 12, he got his first win as a crew chief in the LTi Printing 200 at Michigan with Wallace driving. In 2018, MDM decided to downsize their Truck operation and expand their ARCA team, and Huffman became the crew chief for the part-time No. 12 car driven by Harrison Burton and Brandon Jones. At the start of the season, he remained the crew chief of the No. 99 truck whenever it was entered, the first race being at the spring Martinsville race with Tyler Matthews. However, in the other three races the truck ran that year, Jeff Stankiewicz was the crew chief of the No. 99 instead. MDM shut down in 2019, and Huffman moved to driver-owner Bret Holmes' No. 23 team. Although they did not win a race that year, they finished third in the standings, a career-best for Holmes. Huffman returned to crew chief Holmes in 2020.
Personal life
While attending St. Stephens High School in Hickory, North Carolina, Huffman was a three-year starter for the well respected high school wrestling team. He was instrumental in helping with the success of the team; posting a career record of 59–27 at the 112 lb and 119 lb weight classes, as the team won the Big-6 3A conference championship 2 out of the 3 years he started. He also served as one of the team captains during his senior year. To this day Huffman still ranks high on the individual records lists for the school in Single Season Near Fall Points, Single Season Pins, Single Season Team Points, Career Near Fall Points, Career Pins, Career Team Points, and Career Wins.
