newbie ? about LT1
A 5.7l 94 Caprice is an LT1, the LO5 was last offered in the Caprice in 93.
It was not detuned but rather better matched to the heavier car with highway gears, 2.56-3.08 with 27-28" tall tires means TORQUE was what it needed. It makes slightly more lowend torque at a little lower rpm than the vette/f-body motor and runs on 87 octane.
The "impala" LT1 was standard in the 94-6 wagons Roadmasters and Fleetwoods and those are all usually cheaper than "impala" engines.
The base engine in the Caprice sedan only was a 4.3L L99 that is externally the same as the LT1 and often passed off as such.
The shortblocks are for all practical purposes the same.
Autoparts store has the Caprice Classic LS with a different motor....when I was buying the oil filter he looked it up under Just Caprice ( not classic ) 5.7
