The Cadillac Blackwing V8 (GM RPO LTA) is a twin-turbo DOHC V8 engine that was produced by the Cadillac Division of General Motors solely for use in its CT6-V and CT6-Platinum model years 2019 and 2020. It is a clean sheet engine design, as well as the Division's first ever twin-turbo V8 engine.
A rear wheel drive bellhousing is displayed at right, and the integrated front wheel drive bellhousing is displayed at the lower right (in this case, as a part of the GM 6T70 Transmission). GM 60-Degree 2.8/3.1/3.4/3.5/3.9 L V6 (also used by AMC )
In addition to these issues and the obvious overlap in production costs, the cost of certifying so many different engines for tightening worldwide emissions regulations threatened to become very costly. Thus, by the early 1980s, GM had consolidated its powertrain engineering efforts into a few distinct lines.
It was a 341 cu in (5.6 L) engine and produced 90 hp (67 kW). The same year saw the introduction of the synchromesh transmission. This engine was used in the Series 341 and 341B cars of 1928 and 1929. From 1930 through 1935, Cadillac produced a version with an increased displacement of 353 cu in (5.8 L).
Cadillac 4.1 L engine. A new lighter V8 engine was rushed into production for 1982, the HT-4100 (option code LT8).It was a 4100 cc V8, designed for rear-wheel drive and longitudinal front-wheel drive applications sharing the same "Metric" transmission bellhousing pattern as Buick, Oldsmobile, and Pontiac rear- and front-wheel drivetrains for 2.5 L four-cylinder and 2.8, 3.1, and 3.3 L V6.
It comes standard with a 6-speed Tremec manual transmission and is also available with an optional 10-speed automatic.

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.
Another common problem with the 2001–2006 5.3L engines was cracking cylinder heads. This is commonly called the "Castech Head" failure. GM issued a Technical Service Bulletin on this failure to help service technicians identify the problem. The head casting number (which can be viewed from the passenger side of the vehicle just in front of ...
