Holden Models:
The LS1 was used in a variety of Holden models, including the Commodore (VT II, VX, VY, VZ), Calais, Statesman, and Caprice. 

Power Output:
The power output of the LS1 varied slightly across different models and years, starting around 220kW (295hp) in the VT II and increasing to 235kW (315hp) in the VZ before being replaced by the 6.0L Gen IV V8.
