The Northstar engine is a family of high-performance 90° V engines produced by General Motors between 1993 and 2011. Regarded as GM's most technically complex engine, the original double overhead cam, four valve per cylinder, aluminum block/aluminum head V8 design was developed by Oldsmobile R&D, [citation needed] but is most associated with Cadillac's Northstar series.
After building a limited number of 1.5 L Twin Cams, the bore was increased to 82.55 mm (3 + 1 ⁄ 4 in), raising the capacity to 1.56 L. Assembly of the first 50 engines was contracted out to J.A.Prestwich. Prestwich also machined the raw cylinder head castings (cast by William Mills) on these early twin cam engines.
