LS ENGINE PERFORMANCE BUYERS GUIDE
LSA (6.2L / 376 cu in) – Another supercharged LS, this one was used
in the Cadillac CTS-V and Camaro ZL1. Although similar to the LS9 in
design, it is built with several differences, including hypereutectic pistons
vs. the LS9's forged pistons and a smaller supercharger.
Gen III & amp; Gen IV truck engines – Although performance
car engines typically carried "LS" designations, truck versions were
generally labeled Vortec and were offered in 4.8L, 5.3L, 6.0L and 6.2L
displacements. The 4.8L was made exclusively with an iron block and
the 6.2L was made only with an aluminum block. The 5.3L and 6.0L
versions were manufactured with iron and aluminum blocks.
LT1 Gen V (6.2L / 376 cu in)- Introduced on the seventh-generation
Corvette Stingray, the 6.2L LT1 V-8 is the next chapter of the Chevy
small block engine. It is architecturally similar to the LS family, but with
a unique block casting, cylinder head design, oiling system – including
standard oil-jet piston cooling – and more. It also combines advanced
technologies including direct injection, Active Fuel Management (cylinder
deactivation) and continuously variable valve timing to support an
advanced combustion system.
