The 4.4 L; 267.8 cu in (4,389 cc) engine had the 350's crankshaft stroke of 3.48 in (88.4 mm) and the smallest bore of any small-block, 3.5 in (88 ...
The Chevrolet small-block engine refers to one of the several gasoline-powered vehicle engines manufactured by General Motors.These include: The first or second generation of non-LS Chevrolet small-block engines
A unique intake manifold that used the 48 mm (1.9 in) twin-bore throttle body from the 5.7L TPI Corvette engine was used on the engine's top end. [9] The turbocharged 4.3 L (262 cu in) was last used in the GMC Typhoon in the 1993 model year. The engine produced 280 hp (209 kW) at 4400 rpm and 360 lb⋅ft (488 N⋅m) of torque at 3600 rpm.
The standard engine remained the 350 cu in (5.7 L) small-block V8 with throttle-body fuel injection. A 6.5 L turbocharged Detroit Diesel V8 was added as an option for 1994, with output of 180 horsepower (134 kW) and 360 pound-feet (488 N⋅m) of torque. The diesel engine was available only with a four-speed automatic transmission. [18]
Iron Dukes were fitted with fuel injection (TBI, via a single injector in the throttle body) in 1982. This version was christened the Tech IV, though Car and Driver later ridiculed it as the low-Tech IV. [citation needed] Power output increased to 90 hp (67 kW). [11]
In 1988, it was upgraded with throttle-body fuel injection and roller lifters. For the 1992 Magnum update, the throttle-body fuel injection was upgraded to a multi-port fuel injection system. In 1997, it was then upgraded to sequential fuel injection. The engine was produced through 2003 before it was replaced with the 3.7 L PowerTech V6.
Discontinued were the 229 cu in (3.8 L) V6 and 350 cu in (5.7 L) V8 diesel engines. Introduced in place of the 229 V6 was a 262 cu in (4.3 L) V6 (RPO LB4) that was fuel-injected with throttle-body fuel injection. The small block 305 cu in (5.0 L) V8s included computer-controlled 2-barrel Quadrajet carburetors with an automatic choke to improve ...
In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor.
