Was the Corvette Powerglide different than the standard Chevrolet version? What is the difference? I have a 3789012 main case and 3789080 tail shaft. The assy date on the pan is L 10 3.

It depends what you mean by "different". As a complete ASSEMBLY, the 63-67 Corvette Powerglide transmissions were unique to Corvettes. However, the actual differences could well have been quite minor. You see, when it comes to automatic transmissions there are probably billions of combinations of different internal parts which may be and are "mixed-and-matched" by the car manufacturers to "tailor" a specific transmission for specific vehicle operating requirements. As far as specific internal components go, there are VERY few that are UNIQUELY Corvette. There were, of course, considerable internal differences for small block and big block applications, but big block transmissions were not unique to Corvettes, either; Powerglide-equipped passenger cars of the day used big blocks, too.
There were many iterations of the main case and extension housings used for 62-71 aluminum Powerglide applications. In general, the main cases and extension housings used for 63-67 Corvettes were also used for many other passenger car and light truck applications.In Appreciation of John Hinckley- Top
