The Z28 performance package for these vehicles includes an LT1 engine, which has eight cylinders and a displacement of 5.7 liters. The LT1 engine in a 1993 Camaro has a harmonic balancer, or crankshaft balancer, to reduce the harmonic vibrations that occur when the crankshaft spins rapidly. The crankshaft balancer on the LT1 engine is a weight on the crankshaft hub.
