correct me if i'm wrong, but I believe all the modern era 350s (think roadmaster, fleetwood, and caprice) are basically the same chevy engines. In the big cars, the buick and rear drive cadillac had a throttle body injection 4-bolt 350 in 1992-93, and from 1994-96 the fleetwood, roadmaster, and caprice all had a version of the LT1 corvette 350. (In 91 the buick had a chevy 305, which is the motor the caprice, and the ill-fated oldsmobile version, had until 1994. From '94 to 96 the caprice sedan came standard with a 4.3 V8, not V6, and the LT1 was an option).
well I sorta ran away for a minute there, but those last big wagons, especially the LT1 versions, are another fetish of mine:)
