My manual lists a slightly different advance curve, and a different distributor part number for standard/automatic applications. They are very close on the numbers, so I doubt the horsepower or torque differences could be noticed without a dyno run. Carburetor calibration would probably make a lot more difference than advance curve, IMHO.
