The 3600 LY7 (and derivative LP1) is a member of General Motors's new High Feature (or HFV6) engine family of modern DOHC V6s. This new family of engines was introduced in 1997 with the Cadillac CTS. Holden sells the HFV6 under the name Alloytec. The High Feature moniker on the Holden produced engine is reserved for the twin cam phasing high output version. The block was designed to be expandable from 2.8 L to 4.0 L.

It is a 60° 24-valve design with aluminum block and heads and Sequential Electronic Fuel Injection. Most versions feature continuously variable cam phasing on both intake and exhaust valves and electronic throttle control. Other features include piston oil-jet capability, forged and fillet rolled crankshaft, sinter forged connecting rods, a variable intake manifold, twin knock control sensors and coil-on-plug ignition. It was developed by the same international team responsible for the Ecotec, including the Opel engineers responsible for the 54° V6, with involvement with design and development engineering from Ricardo plc.

High Feature V6 engines are produced at the following four manufacturing locations: Fishermans Bend, Port Melbourne, Australia; St. Catharines, Canada; Flint Engine South in Flint, Michigan, United States; and Ramos Arizpe, Coahuila, Mexico. The assembly lines for the St. Catharines and Flint facilities were manufactured by Hirata Corporation at their powertrain facility in Kumamoto, Japan. Most of the designs of this motor happened in Flint. They were first produced for the Cadillac range.
