[9] The later 4.3-liter V6 engine, which arrived for the 1982 model year, did not have the same problems as the V8. The V6 has a denser bolt pattern and Oldsmobile's engineers were given more time to develop and test it. [8]

Many car enthusiasts also desired a dual overhead cam engine; [26] GM in response had developed the Northstar engines for Cadillac, but those engines were initially exclusive to that brand and not originally designed for rear-wheel-drive vehicles.

These engines were used by IHC for some heavy-duty applications until 1935, although their own large engines (525 cu in (8.6 L) FBD and 648 cu in (10.6 L) FEB) had appeared in 1932. [6] The medium-duty 1930 A-series trucks received the all-new 278.7 cu in (4.6 L) FB-3 six-cylinder engine, with overhead valves and seven main bearings .
The metric 200 three-speed automatic transmission became standard on all models and a new Chevrolet-built 229 cu in (3.8 L) V6 with 2-barrel Rochester carburetor replaced both the 200 cu in (3.3 L) V6 of 1979 and the Buick engine offered on all 1978 models and the 1979 Landau as the standard engine in 49 states (California cars continued to use ...
With an unmodified car and a test weight of 4,010 lbs the testers clocked 14.25 seconds at 101 mph. The car had a Turbo-Hydramatic 400 3-speed automatic transmission and came equipped with air conditioning, an option that added considerable weight to the car and engine. [30] Output was 290 hp (216 kW) at 4,400 RPM.
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.
