GM/Chevrolet 5.7 350 LT1 - Production Years 1992-1997

Description

The Chevy 350 LT1–not to be confused with the LT-1–was in production between 1992 and 1997.

It marks a return to form for the 350, which had languished in the 1980s under more rigorous federal emissions regulations.

The LT1 is capable of producing a lot of power, thanks to its reverse cooling system that allowed the engine to run at a higher compression than its predecessors.

In 1996-1997, some Corvettes, Camaros, and Firebirds with 6-speed manual transmissions were designated LT4. Fewer than 7 thousand of these were produced at the time.

2-Bolt Chevy 350s

2-Bolt Chevy/GM 350 LT1 are far more common. They came in most every vehicle aside from the Chevrolet Corvette.

The bolt pattern remains consistent with former patterns, allowing this engine to be placed into older model vehicles.

4-Bolt Chevy 350s

From the factory, 4-bolt Chevy/GM 350 LT1s were included in the Chevrolet Corvette. This is because the improvements to the engine during this time period exceeded the horsepower standards of the 2-bolt variations.

High-performance 350s should have 4-bolts.
