I have a book aout Chevys police cars and it say that its a 205hp 5.7l RPO=LO5 tranny 4spd AOD Axle 3.42
Thoses infos come from the 1992 vehicule testeing and evaluation program los angeles county sherrif department

MORE INFOS

The package included a Y-pipe,collector and exhaust pipes with less restrictive catalytic converter that made the backpressure drop from 21 inches of mercury to 15 inches.
Also had a fresh air intake to allow cooler more dense air and allow more spark advance before detonation occur.

Finally in 1992 they tested a motor that will be later use in the Camaro B4C 1993 and in the Caprice 1994. It' the LT1 that is sequentially injected,tuned port 350,dual exhaust. This motor devellop 280hp.The 1994 Caprice with the LT1 package go 2 seconds fater than the 1992 Caprice with the LO5 package so think about it at your next swap
