For this inline-4 engine, 1-3-4-2 could be a valid firing order. The firing order of an internal combustion engine is the sequence of ignition for the cylinders. In a spark ignition (e.g. gasoline/petrol) engine, the firing order corresponds to the order in which the spark plugs are operated. In a diesel engine, the firing order corresponds to ...
Pontiac engines were used in its U.S.-market cars; Canadian-built Pontiac automobiles generally used Chevrolet engines. From 1955 through 1959, the Pontiac V8 was also used in some GMC pick-up trucks including the 1958/59 336 cubic-inch versions of the 370CI and 389CI engines. Federal emissions standards and the drive towards "corporate ...
Chevrolet, as an entry-level marque, did not have a straight-eight. Cadillac, the luxury brand of General Motors, stayed with their traditional V8 engines. In order to have engines as smooth as the straight-eights of its competitors, Cadillac introduced the crossplane crankshaft for its V8, and added V12 and V16 engines to the top of its lineup.

Hyundai told safety regulators the same metal debris problem caused the expanded recall. Near that same time, Kia told NHTSA about a recall of more than 618,000 model year 2011-2014 Kia Optima, 2012-2014 Sorento and 2011-2013 Sportage vehicles because the Theta engine bearings wore out too early and caused the engines to seize.

For 1958, GMC reduced the bore of Pontiac's 370-cubic-inch (6.1 L) to 3.875 in (98.4 mm), resulting in a displacement of 336-cubic-inch (5.5 L). (In Canada, however, GMC used the Chevrolet small-block engine rather than the Pontiac.) For 1959, as the Pontiac engine's stroke was lengthened to 3.75 in (95.3 mm), a further bore reduction to 3.78 ...
90° V angle: This design historically derives from chopping two cylinders off a 90° V8 engine, in order to reduce design and construction costs. An early example is the 3.3 L (200 cu in) and 3.8 L (229 cu in) Chevrolet 90° V6 engines , which have an 18° offset crankshaft resulting in an uneven firing interval.
