1981-1986 in most cars, 1981-1986 CCC Q-Jet trucks for California, 1985-1986 TPI, Vettes used a little different style until the LT1 was introduced in 1992. Make sure that you don't get a 1981-1986 federal emission 305 truck/van/suburban unit. It has the EST style 4 pin flat connector, but has centrifical and vacuum advance mechanism's.
