from 96-present all GM gasoline truck/van V6 and V8 motors are known as Vortec motors however.. in 99 GM started using a new motor that isn't like the old 350s but like the new LS1 style motors they are also known as vortec motors.



The V8 vortec motors are Generation I and Generation III/IV.. Generation 1 vortec motors were produced from 96-03 and were offered in displacements of 5.0l and 5.7l.. Generation III/IV vortec motors were/are offered in displacements of 4.8l, 5.3l, 6.0l, and 6.2l..



The V6 vortec motors were only offered in a 4.3l displacement
