LT1 CORVETTE

Chevrolet's first attempt at a redesign of the small block came in 1992 with the introduction of the LT1.
Cast iron block with aluminum heads, the biggest change is in the water passages. Called reverse cooling, it routed the water to the heads first. Then into the block. This aided in preventing detonation by keeping the heads cooler. Also, the water pump is driven by a gear. Which is turned by the camshaft sprocket.
