I didn't find that number in my book, but from what it lools like it was for 1970 to 1985 Buick, Cadallac, Pontiac, Olds and GMC V6 and V8 motors. Then I found an add that had a 65 corvette with a 327 that has that starter number listed as being date correct for the car. It also looks like the question was asked before with no luck. Here's the link to the car.
