JBA Racing is the premier Ford 4.6L modular high performance street and race engine builder. For more than two years, a JBA-built 4.6L 4v mod motor has been competing in championship-level road racing with zero failures and producing nearly 1,000 race laps, nine race wins, twelve additional podium positions and four track records in the highly competitive National Auto Sports Association Pro Racing American Iron series.

After 800 laps spread over fifteen race days, the JBA engine team disassembled and inspected the motor. Amazingly, they found bearings, pistons, rods and other internal components in near-perfect condition. Needless to say, this is virtually unheard of in high performance racing, where engines are often rebuilt or replaced after each race in order to ensure survival.
