For the new Generation IV V8, see GM L98. Years: 1985-1992
The new 1985 L98 added tuned-port fuel injection "TPI", which produced 230 hp (172 kW) and 330 ft·lbf (447 N·m). It was standard on all 1985-1991 Corvettes (rated at 230-250 hp and 330-350ft·lbf torque). Optional on 87-92 Chevrolet Camaro & Pontiac Firebird models (rated at 225-245 hp and 330-345ft·lbf torque) 1987 versions had 10 hp (7.5 kW) and 15 ft·lbf (20 N·m) more thanks to 9.5:1 compression. Compression was up again in 1991 to 10:1 but output stayed the same.
[edit] L98
For the tuned-port Generation I engine of the same RPO, see Chevrolet L98 The L98 is a slightly modified version of the L76, devoid of some redundant hardware relating to displacement on demand. Power increased to 362 hp (270 kW) at 5700 rpm and 391 ft·lbf (530 Nm) at 4400 rpm.
