Siscone began his racing career driving go-karts from 1962-1969. He and his father had 90 victories including IKF State and Regional karting titles. Siscone and his father, Tony Sr., competed several times in IKF National Championship go-kart events against factory backed teams, finishing tenth, sixth and fourth.
Siscone began his stock car racing career in 1972, driving the Richie Terruso Brothers' #T3 sportsman car to eight victories at Atlantic City Speedway and Wall Stadium. Siscone won his first track championship in 1974, driving the #T4 owned by his father and Tony Ruberti at the Atlantic City Speedway. During 1975 & 1976, Siscone drove the #65 car owned by John Lyons and powered by a Tom Skinner/Lyons Chevy racing engine to 12 victories and his second championship. In 1978, Siscone drove the #21X owned by Ed Brown/John Lyons to six wins, and the #21 owned by Sal DeBruno to four wins. The two cars won every race they finished, resulting in Siscone's 3rd track championship at the Atlantic City Speedway.
From 1973-1975, Siscone struggled to get his modified stock car career on track. The Terruso brothers gave Siscone his first opportunity to compete in the modified ranks driving their modified #T2. As time went on, the team realized they lacked the finances to compete with the top teams. During the 1975 season, Siscone and the Terruso team parted ways, and Siscone went on to drive for anyone who would to give him a chance. After 3 Modified seasons, 64 starts, Siscone had only six-top-five finishes, three-second place finishes and three third place finishes and no wins. Midway through the 1976 season at Wall Stadium, Siscone landed a ride in Tom Green's #71 modified. Siscone wheeled the "Green Machine" to six top-five finishes but still failed to reach victory lane.
In 1977, after four modified seasons, fellow Hammontonian Frank Ransom offered Siscone the ride in his controversial #0 NASCAR Modified. The Ransom/Siscone Team WON 3 modified events with a 355 CI small block Chevy engine against the big block modifieds at Wall Stadium and NASCAR's New Egypt Speedway. In April 1978, opening night at Wall Stadium, the Ransom/Siscone team won the modified main event. four days after celebrating their big win, car owner Frank Ransom passed away. Siscone and Team Ransom were devastated. After three months without a modified ride at Wall Stadium, Siscone was given the chance to drive the Fred & Kathy Burdge #57 modified. After 11 races, the Burdge/Siscone team ended the season with three top-five finishes, six top-ten finishes and no wins.
In August 1978, car owner Dick Barney, Robert Barney, and Hoyt Morrison offered Siscone the chance to drive their #14 modified car during the last six races of the season at NASCAR's New Egypt Speedway. Siscone finished all six races in the top-five. The Barney/Morrison team wrapped up the 1978 season at Wall Stadium's "Turkey Derby 150". Siscone started 23rd in the Derby and charged to a fifth place finish. Needless to say, Siscone continued to drive the #14 for the next 16 years.
In 1982, Siscone was involved in a violent crash with Ray Evernham's #19 modified at the Martinsville Speedway. The accident occurred on lap 166 of the 250-lap race. Evernham's car stalled out, and Siscone crashed into him, causing a large, firery explosion. While Evernham only suffered minor burns, Siscone suffered third degree burns to both of his hands.[3] The following year, 1983, was the Team's "comeback season". The Barney/Siscone Team went on to win the New Egypt Speedway NASCAR Championship, finishing in the top-three in every race with no DNFs. The Barney/Siscone Team also won the 1983 Wall Stadium Modified Championship. Despite his previous injuries, Siscone returned to the Martinsville Speedway in 1984, two years after grafting surgery to both hands. The team competed in NASCAR's Modified "Cardinal 250", and won the prestigious event!
Siscone, surprisingly, retired from racing in 1994 after winning the "Sunoco Race of Champions 250" at the Flemington Speedway. The Barney/Siscone Team became the only New Jersey Modified Team to ever win both the "Cardinal 250" at the Martinsville Speedway and the "Modified Race of Champions 250".
