The 3600 LY7 (and LP1 ) is a member of the new General Motors family High Feature (or HFV6 engine) DOHC V6s modern. The new engine family was introduced in 2004 with Cadillac CTS. Holden sells HFV6 under the name Alloytec . The Higher Feature moniker on a machine produced by Holden is reserved for a high output version of twin cam phasing. This block is designed to be expandable from 2.8 Ã, Â ° C to 4.0Ã, L.
It is a 60  ° 24-valve design with block and aluminum head and Sequential Electronic Fuel Injection. Most versions feature continuous variable cam focusing on input and exhaust valves as well as electronic throttle controls. Other features include the ability of oil-jet pistons, forged crankshaft and crankshaft fillets, sinter forged connecting rods, variable-length intake manifolds, twin tap control sensors and coil-on-plug ignition. It was developed by the same international team responsible for Ecotec, including the Opel engineer responsible for 54Ã, ° V6, with an engagement with the design and development techniques of Ricardo plc.
The High Feature V6 engine was previously manufactured at Fisherman Bend, Port Melbourne, Australia and remained in production at the following four manufacturing sites: St. Catharines, Canada; Flint Engine South in Flint, Michigan, United States; Romulus Engine Plant in Romulus, MI and Ramos Arizpe, Coahuila, Mexico. Assembly line for St. Catharines and Flint are manufactured by Hirata Corporation in their powertrain facility in Kumamoto, Japan. Most of these motor designs occur in Flint. They were first produced for the Cadillac range.

History
The HFV6 was first designed, tested and produced in a joint program by Cadillac and Holden. Most of the designs into new alloy construction, transmission pairs and first use in production are all done in Detroit (and manufactured in St. Catharines). Holden has the task of developing smaller engines (Holden 3.2, LP1 and Saab 2.8, LP9 Turbo) and Holden 3.6 HFV6 (called Alloytec V6) for local models.
Cadillac and Holden both test variations of this engine in the US and Australia.
