Factory original three-groove 7 5/8 inch diameter air conditioning pulley for big block engines: 396, 402, 427 and 454. Part number 3937787-AC is stamped right into it (that's what the arrow is pointing at in Photo 3). NOT a lightweight modern Chinese reproduction that doesn't align properly. Requires the use of a long water pump. Although this pulley can be installed on many other big block vehicles, the correct OEM applications are: 1969, 1970, 1971 and 1972 Chevelle and El Camino including SS; 1969, 1970, 1971 and 1972 Camaro RS and SS; 1969, 1970, 1971 and 1972 Chevrolet full size including Impala and Caprice; as well as Chevrolet and GMC trucks in 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980, 1981, 1982, 1983, 1984 and 1985.
