Product Description

The Vortec 5300, or LM7/L59/LM4, is a V8 truck engine. It is a longer-stroked (by 9 mm (0.35 in)) version of the Vortec 4800
and replaced the L31. L59 denoted a flexible fuel version of the standard fuel LM7 engine.
Displacement is 5.3 L (5,328 cc (325.1 cu in)) from 3.78-inch (96 mm) bore and 3.622-inch (92.0 mm) stroke.
Vortec 5300s are built in St. Catharines, Ontario and Romulus, Michigan.
Another engine variant, the L33, shares the same displacement, but has an aluminum block with cast in cylinder liners, much like the LS1.
