All the engines use a 1-6-5-4-3-2 firing order. [2] The engines in this family are longitudinal engines, and have been used in rear-wheel drive cars and trucks, industrial, and marine applications. Until 2014, the Chevrolet 90° V6 was produced at the GM Powertrain Division plant in Romulus, Michigan.
The 229 cu in (3.8 L) Chevrolet V6 was essentially a small block Chevy V8 missing two cylinders. 1978–1987 Chevrolet Monte Carlo This is very confusing, as Monte Carlo at various times used both the V6 from the Buick engine as well as the V6 engine derived from the Chevrolet V8. 1978–1980 Chevrolet Monza; 1978–1987 Oldsmobile Cutlass Supreme
This was Chevrolet's second 4.3L power plant; four other Chevrolet engines displaced 4.3L: the Vortec 4300 (a V6 based on the Chevrolet 350 cu in (5.7 L), with two cylinders removed), the original 265 cu in (4.3 L) V8 in 1954, a bored version of the stovebolt-era 235 inline six displacing 261 cu in (4.3 L), and a derivative of the Generation II ...
The 153 cu in engine had a 3 + 7 ⁄ 8-inch (98 mm) bore and 3 + 1 ⁄ 4-inch (82.6 mm) stroke, with two overhead valves per cylinder actuated by pushrods and a 1-3-4-2 firing order. The Chevy II 's 194 cu in six-cylinder used a 3 + 9 ⁄ 16 -inch (90.5 mm) bore, which by 1964 was enlarged to match the 153 four-cylinder's resulting in a ...
The Group 1 engines were the smallest in displacement and outer dimensions, and differed most significantly from the larger Group 2 and Group 3 engines by having only four main bearings (whereas the Group 2 and 3 engines had seven) [1]: 15 and a different firing order (1-5-3-6-2-4, whereas the others are 1-4-2-6-3-5).
Pontiac's 215 cu in (3.5 L) (1964–1965) was a smaller bore of 3.75 in (95.25 mm) version of the 230 cu in (3.8 L) Chevrolet straight-six engine. One oddity is the crankshaft bolt pattern; in lieu of the Chevrolet V8 bolt pattern (also shared with the rest of the third-generation six), the Pontiac V8 bolt pattern is used.
The cylinder firing order was changed to 1-8-7-2-6-5-4-3 [43] so that the LS series now corresponds to the firing pattern of other modern V8 engines (for example the Ford Modular V8). 3.898 in. bore blocks (1997–2005)
Sometimes confused with the Buick designed and built 215 cu in (3.5 L) aluminum V8 that Pontiac had used in the two years prior, the "Pontiac 215" was an adaptation of Chevrolet's 194 cu.in. inline 6 currently produced and the new 230 cu in (3.8 L) overhead valve Turbo-Thrift straight-6.
