1992 LT1 (350CI) Engine Guide: Specs, Features, & More

By the early 1990s, talk had begun to center around the potential release of the fifth-generation Corvette. By this time, the C4 Corvette had already weathered the 1980s, leaving many to wonder when the next generational divide might take place. However, those at the helm of GM ultimately decided to postpone the release of their fifth-generation Corvette, largely due to budgetary constraints of the day.

However, the development of a new powerplant for the aging C4 Corvette was greenlighted nonetheless. This engine would ultimately carry the LT1 designation, and prove quite capable beneath the Corvette’s hood. The 1992 LT1 would serve as a bridge between GM small-block development, past and present.

LT1 History

Throughout the years, the Corvette has been powered by its fair share of memorable small-blocks. Though initially equipped with a 150 horsepower inline-six, “Blue-Flame” engine, the Corvette began being offered with an optional 265 cubic-inch small-block V8 in 1955.

The introduction of this engine would drastically alter the trajectory of subsequent Corvette sales, even saving the fledgling sports car from a near-certain demise during its earliest days of production.
