Cloyes 9-3100BZ timing set for the 1959-1967 Chevrolet Impala V8 4.6L, the 1962-1969 Impala V8 5.3L, the 1968 Impala V8 5.0L, the 1969-1971 Impala V8 5.7L, the 1970-1976 Impala V8 6.6L, the 1974-1982 Impala V8 5.7L, the 1979-1984 Impala V8 5.0L, the 1980-1982 Impala V8 4.4L, the 1980-1984 Impala V6 3.8L and other vehicles links the crankshaft to the camshaft so the valves open and close in time with the pistons. This Cloyes Hex-A-Just timing set comes as three pieces, hand-matched to qualify the correct center distance and minimize runout.
- Hex-A-Just design allows infinite valve timing adjustability of +/-6 degrees
- One-piece camshaft sprocket with a billet eccentric camshaft dowel bushing
- Both billet steel sprockets are heat treated for durability
- True roller "Z" chain with a 0.250 in roller diameter for reduced friction
- Press-fit center link design on the "Z" chain spreads load, with heat-treated, pre-stressed links
- Captured needle camshaft sprocket thrust bearing reduces friction at the block thrust surface

The "Z" chain is approximately 33% stronger overall than the standard high performance chain. Signs of a worn engine timing set can include a rattle from the front of the engine or timing that wanders. These signs alone do not prove the timing set is the problem, since worn ignition parts can cause rough running too.
Fits
This set also fits the 1978-1979 Chevrolet Malibu V6 3.3L, the 1978-1981 Malibu V8 5.7L, the 1979-1982 Malibu V8 4.4L, the 1979-1983 Malibu V8 5.0L and the 1980-1983 Malibu V6 3.8L, as well as the 1961-1966 Chevrolet Suburban V8 4.6L and the 1966 Suburban V8 5.3L. Each application takes one set. For any other car, look up its year and engine in the "Vehicles it fits" section.
