The LS3 Engine was First Introduced in the HSV VE Series 2 Range. It has since been used only in the HSV Range until current in the New Gen-F Range.
The 6.2Litre 376ci Engine is a great starting point for performance upgrades.
The L98 Engine has been used from VZ to the VE-VF Range. Its 6.0 364ci capacity makes great power in standard form but really comes alive once the Camshaft Package has been upgraded.
