The mighty L98 Tuned Port Injection (TPI) 5.7L small-block was unveiled as a Corvette- only powerplant in 1985 and delivered a heady 230 hp, and, more important, 330 lb-ft of torque. As Ford’s Mustang GT and LX grew more potent with each passing year, rumors swirled that Camaro and Firebird would soon offer the L98 to keep pace. In 1987, GM delivered, and torque monster L98-powered F-bodies began making Ford drivers sweat a little more. Of the various 350-powered Firebird models available (Trans Am, GTA and Formula), the Formula 350 offered the best bang for the buck. Consider this: an L98-powered Firebird GTA cost $20,339 versus $13,949 for the Formula 350. Sadly, this sleek black Formula’s Mustang taunting days are over.
