The L03 produced 170 hp (127 kW) at 4400 rpm and 255 lb⋅ft (346 N⋅m) of torque at 2400 rpm in 1993–1995 GM trucks. This engine used the TBI throttle body fuel injection, which was a hybrid between EFI and carburetor technology. It used an EFI system with electronically controlled injectors, which were mated to a twin barrel "carburetor" body.
In 1991, the Oldsmobile 307 was replaced with a 305 cu in (5.0 L) throttle body fuel-injected small-block Chevrolet L03 V8, which was also found in Chevrolet's Caprice, C/K light trucks, and G-series vans. In 1993, the 180 hp (134 kW) 350 cu in (5.7 L) L05 V8 became standard in the newly-renamed Cadillac Fleetwood.
Several significant changes were made in 1987, which included: an improved cylinder head, intake manifold, and throttle-body fuel injection module; a more-modern serpentine belt with an automatic spring-loaded tensioner for the accessories; and a Distributorless Ignition System (DIS). This revision to the engine increased power to 98 hp (73 kW).
For the 1990 model year, GM replaced the 2.0-liter engine with a stroked version displacing 2.2 liters and using throttle-body fuel injection (TBI). Commonly called the 2.2, it produced 95 hp (71 kW) and 120 lb⋅ft (163 N⋅m) of torque. Applications: 1990–1991 Chevrolet Beretta; 1990–1991 Chevrolet Cavalier; 1990–1991 Chevrolet Corsica
In the US, this kind of single-point injection was marketed as 'throttle body injection' (TBI, by GM), or 'central fuel injection' (CFI, by Ford). Mono-Jetronic is different from all other known single-point systems, in that it only relies on a throttle position sensor for judging the engine load.
For 1991, the 700R4 was renamed to the 4L60. The TBI (throttle body injection) system used on the Blazer's standard 5.7 liter V8 had longer throttle shaft bearings, new throttle return springs, and improved fuel mixture distribution. The 5.7 liter V8 also had new heavy-duty intake valves and powdered metal camshaft sprockets.
The Chevrolet Van or Chevy Van (also known as the Chevrolet/GMC G-series vans and GMC Vandura) is a range of vans that was manufactured by General Motors from the 1964 to 1996 model years. Introduced as the successor for the rear-engine Corvair Corvan/Greenbrier , the model line also replaced the panel van configuration of the Chevrolet Suburban .
The GM Family I is a straight-four piston engine that was developed by Opel, a former subsidiary of General Motors and now a subsidiary of PSA Group, to replace the Vauxhall OHV, Opel OHV and the smaller capacity Opel CIH engines for use on small to mid-range cars from Opel/Vauxhall.
