I assume these are GM 454, 7.4L, gas engines. The '91 is probably "TBI" (throttle body injection). Somewhere later in the 90's, I think the fuel system was changed to port injection, and the engine type was advertised as "Vortec", which had more power and possibly better mileage. This is all from memory, so someone correct me if I am wrong.
