The engine had MPFI (multi-port fuel injection), which gave slightly more power and better fuel economy, and two valves per cylinder. The engine had a bore and stroke of 4 + 1 ⁄ 4 in × 4 in (108.0 mm × 101.6 mm), producing 290 hp (216 kW) at 4000 rpm and 410 lb⋅ft (556 N⋅m) at 3200 rpm. It was used by Mercury Marine, named the ...
The engines were also sold for marine and stationary applications. In a 1938 reorganization, Winton Engine Corporation became the GM Cleveland Diesel Engine Division, and GM's Detroit Diesel Engine Division began production of smaller (50–149 cu in (0.8–2.4 L) per cylinder) diesel engines. Locomotive engines were moved under the GM Electro ...
The engine was also used in the Buick Rainier, Saab 9-7X, and Isuzu Ascender. It displaces 4.2 L (4,160 cc; 253.9 cu in), with a 93 mm × 102 mm (3.66 in × 4.02 in) bore and stroke. It has four valves per cylinder, utilizes dual-overhead cams ( DOHC ) design, and features variable valve timing on the exhaust cam, a first for GM inline engines.

[28] LT9 engines were carbureted with Rochester Quadrajets from the factory and generally have four-bolt mains. The LT9 is often known as the "M-code 350," from the eighth character of the VIN. [27]
Some 1985 model year vehicles would have a 1986 engine due to service replacement – cylinder blocks were shipped with oil pans. [3] 1987 saw new center bolt valve covers and hydraulic roller lifters. [4] For the 1992 model year, the 4.3 L (262 cu in) had its block design modified to allow a balance shaft to be installed. [5]
Vortec is a trademarked name for a line of gasoline engines for General Motors trucks.The name first appeared in an advertisement for the 1985 model year 4.3 L V6 that used "vortex technology" to create a vortex inside the combustion chamber, creating a better air / fuel atomization. [1]
