Here's a bit of information on the changes in the 5.7 from 1993 to 1994.
--------------------------------------------------------------------
Year-to-year changes
1992: A 4-door sedan joined the Roadmaster wagon as an early 1992 model, carrying the 5.7 L TBI (Throttle-Body Injection) V8 engine that developed 180 hp. That engine also went into the Estate Wagon, replacing the 5.0 L.
1993: Window lockout feature and the addition of a new spoke wheel cover mid-year.
1994: A redesigned dashboard included a new instrument cluster, with climate controls mounted higher and a knee bolster below. Dual airbags were also installed. The 5.7L TBI is replaced with a detuned 5.7L LT1 engine from the Chevrolet Corvette. This LT1 had cast iron cylinder heads and produced 260 hp (194 kW) (40 less horsepower than the Corvette). A new electronically-controlled 4L60-E 4-speed automatic transmission replaces the 4L60.
