L44
The L44 was produced from 1985 to 1988. It used MFI and was a High Output engine for the Pontiac Fiero. This engine created 140 hp (100 kW ) @ 5000 rpm and 170 lb-ft (230 Nm) of torque @ 3600 rpm. It also used the same camshaft as the 3.4L V6 that was installed in later Camaros and Firebirds. The heads on this engine also had slightly larger ports as well as larger valves than all other 2.8L engines. These heads were used on the larger 3.4L V6s that came in later Camaros and Firebirds.
