There are two designs of distributors for our V6 engines. 1960-1963 uses a window-type distributor using a V8 design. If you need an advance for these year model engines, you can use one for any GM V8 engine (I used one listed for a v8-283 on my V6-305 using the window-type distributor). 1964-1974 uses the I-6 23-250-292 design distributor and the advance listed for the chev. engine will work on the later distributors. One thing I didn't mention is that I cut the metal vacuum line in order to use a rubber vacuum hose.
