Below: As a new car, the Firebird Formula 350 was the best big-engine-in-small-car themed performance model of the decade. The 5.0L Mustang LX may have been quicker, but it wasn’t nearly as intimidating. Enjoying a six-year production run from 1987 through 1992, the Formula 350 was essentially a stripped down Firebird with a Corvette 350. The only hassle was that these 5.7L wailers were an automatic-only proposition; the five-speed stick was only available in lesser 205hp LB9 305-powered Firebird Formulas. Verifying an actual 5.7-powered Formula 350 is as simple as checking the eighth symbol of the VIN for the number 8. For example, this ’89 wears the CC1 T-top roof, a $920 option that was shunned by the more hard-core street racers for its added heft and flex-inducing attributes.
