Not to be outdone by Chrysler, Ford had to build and field its own race-duty big-block to compete with the 426 Hemi in drag, and stock car racing. In competition trim, the Boss 429 powered Ford and Mercury stock cars to victory in NASCAR, and the Mustang to many wins in drag racing. With this exclusive racing pedigree, the Boss 429 is one of the most valuable, and rare Mustangs ever built.
